NAME

       wwwoffle.conf  -  The  configuration  file for the proxy server for the
       World Wide Web Offline Explorer.

Introduction

       The  configuration  file  (  wwwoffle.conf  )  specifies  all  of   the
       parameters that control the operation of the proxy server.  The file is
       split into sections each containing a series of parameters as described
       below.  The file CHANGES.CONF explains the changes in the configuration
       file between this version of the program and previous ones.

       The file is split into sections, each of which can be empty or  contain
       one or more lines of configuration information.  The sections are named
       and the order that they appear in the file is not important.

       The general format of each of the sections is the same.   The  name  of
       the  section is on a line by itself to mark the start.  The contents of
       the section are enclosed between a pair of lines  containing  only  the
       '{' and '}' characters or the '[' and ']' characters.  When the '{' and
       '}'  characters  are  used  the  lines  between  contain  configuration
       information.   When the '[' and ']' characters are used then there must
       only be a single non-empty line between them that contains the name  of
       a file (in the same directory) containing the configuration information
       for the section.

       Comments are marked by a '#' character at the start  of  the  line  and
       they are ignored.  Blank lines are also allowed and ignored.

       The phrases URL-SPECIFICATION (or URL-SPEC for short) and WILDCARD have
       specific meanings in the configuration file and are  described  at  the
       end.   Any  item enclosed in '(' and ')' in the descriptions means that
       it is a parameter supplied by the user, anything enclosed  in  '['  and
       ']'  is  optional,  the '|' symbol is used to denote alternate choices.
       Some options apply to specific URLs only, this is indicated by having a
       URL-SPECIFICATION  enclosed  between '<' & '>' in the option, the first
       URL-SPECIFICATION to match is used.  If no URL-SPECIFICATION  is  given
       then it matches all URLs.

StartUp

       This  contains  the  parameters  that are used when the program starts,
       changes to these are ignored if the configuration file is re-read while
       the program is running.

       bind-ipv4 = (hostname) | (ip-address) | none
              Specify  the  hostname  or IP address to bind the HTTP proxy and
              WWWOFFLE control port sockets to using IPv4 (default='0.0.0.0').
              If 'none' is specified then no IPv4 socket is bound.  If this is
              changed from the default value  then  the  first  entry  in  the
              LocalHost section may need to be changed to match.

       bind-ipv6 = (hostname) | (ip-address) | none
              Specify  the  hostname  or IP address to bind the HTTP proxy and
              WWWOFFLE control port sockets to  using  IPv6  (default='none').
              If  'none'  is  specified  then  no  IPv6 socket is bound.  This
              requires the IPv6 compilation option.  If this is  changed  from
              the  default value then the first entry in the LocalHost section
              may need to be changed to match.

       http-port = (port)
              An integer specifying the port number for connections to  access
              the  internal  WWWOFFLE  pages  and  for HTTP/HTTPS/FTP proxying
              (default=8080).  This is the port number that must be  specified
              in   the   client   to   connect   to  the  WWWOFFLE  proxy  for
              HTTP/HTTPS/FTP proxying.

       https-port = (port)
              An integer specifying the port number for encrypted  connections
              to  access the internal WWWOFFLE pages and for HTTP/FTP proxying
              (default=8443).  Requires gnutls compilation option.

       wwwoffle-port = (port)
              An integer specifying the port number for the  WWWOFFLE  control
              connections to use (default=8081).

       spool-dir = (dir)
              The  full  pathname  of  the  top  level  cache directory (spool
              directory) (default=/var/cache/wwwoffle  or  whatever  was  used
              when the program was compiled).

       run-uid = (user) | (uid)
              The  username  or  numeric  uid  to  change to when the WWWOFFLE
              server is started (default=none).  This option only works if the
              server is started by the root user on UNIX-like systems.

       run-gid = (group) | (gid)
              The  group  name  or  numeric gid to change to when the WWWOFFLE
              server is started (default=none).  This option only works if the
              server is started by the root user on UNIX-like systems.

       use-syslog = yes | no
              Whether   to  use  the  syslog  facility  for  messages  or  not
              (default=yes).

       password = (word)
              The password used for authentication of the control  pages,  for
              deleting  cached  pages etc (default=none).  For the password to
              be secure the configuration  file  must  be  set  so  that  only
              authorised users can read it.

       max-servers = (integer)
              The  maximum  number  of  server  processes that are started for
              online and automatic fetching (default=8).

       max-fetch-servers = (integer)
              The maximum number of server processes that are started to fetch
              pages  that were marked in offline mode (default=4).  This value
              must be less than max-servers or you will not  be  able  to  use
              WWWOFFLE interactively online while fetching.

Options

       connect-timeout = (time)
              The time in seconds that  WWWOFFLE  will  wait  for  the  socket
              connection to be made before giving up (default=30).

       connect-retry = yes | no
              If  a connection cannot be made to a remote server then WWWOFFLE
              should try again after a short delay (default=no).

       dir-perm = (octal int)
              The directory permissions to use when creating spool directories
              (default=0755).  This option overrides the umask of the user and
              must be in octal starting with a '0'.

       file-perm = (octal int)

              "fetch".

       run-fetch = (filename)
              The  full  pathname  of  a  program to run when a WWWOFFLE fetch
              starts or stops (default=none).  The program is started  in  the

              process   from  downloading  the  same  URL  at  the  same  time
              (default=no).  Disabling the lock-files may result in incomplete
              pages  being  displayed  or  many  copies  being  downloaded  if
              multiple requests are made for the same URL at the same time.

       reply-compressed-data = yes | no
              If the replies that are  made  to  the  client  are  to  contain
              compressed  data  when  requested  (default=no).   Requires zlib
              compilation option.

OnlineOptions

       Options that control how WWWOFFLE behaves when it is online.

       [<URL-SPEC>] pragma-no-cache = yes | no
              Whether to request a new copy of a page if the request from  the
              client  has 'Pragma: no-cache' (default=yes).  This option takes
              precedence over  the  request-changed  and  request-changed-once
              options.

       [<URL-SPEC>] cache-control-no-cache = yes | no
              Whether  to request a new copy of a page if the request from the
              client has 'Cache-Control: no-cache' (default=yes).  This option
              takes     precedence     over     the     request-changed    and
              request-changed-once options.

       [<URL-SPEC>] cache-control-max-age-0 = yes | no
              Whether to request a new copy of a page if the request from  the
              client   has  'Cache-Control:  max-age=0'  (default=yes).   This
              option   takes   precedence   over   the   request-changed   and
              request-changed-once options.

       [<URL-SPEC>] cookies-force-refresh = yes | no
              Whether  to  force the refresh of a page if the request from the
              client  contains  a  cookie  (default=no).   This  option  takes
              precedence  over  the  request-changed  and request-changed-once
              options.

       [<URL-SPEC>] request-changed = (time)
              While online pages will only be fetched if the cached version is
              older   than  this  specified  time  in  seconds  (default=600).
              Setting this value negative will indicate that cached pages  are
              always  used while online.  Longer times can be specified with a
              'm', 'h', 'd' or 'w' suffix for minutes, hours,  days  or  weeks
              (e.g. 10m=600).

       [<URL-SPEC>] request-changed-once = yes | no
              While  online  pages  will only be fetched if the cached version
              has  not  already  been  fetched  once   this   session   online
              (default=yes).    This   option   takes   precedence   over  the
              request-changed option.

       [<URL-SPEC>] request-expired = yes | no
              While online pages that have expired will  always  be  requested
              again  (default=no).   This  option  takes  precedence  over the
              request-changed and request-changed-once options.

       [<URL-SPEC>] request-no-cache = yes | no
              While online pages that ask not to  be  cached  will  always  be
              requested again (default=no).  This option takes precedence over
              the request-changed and request-changed-once options.

       [<URL-SPEC>] request-redirection = yes | no
              While online pages that  redirect  the  client  to  another  URL
              temporarily  will be requested again. (default=no).  This option
              takes    precedence     over     the     request-changed     and
              request-changed-once options.

       [<URL-SPEC>] request-conditional = yes | no
              While  online  pages  that are requested from the server will be
              conditional requests so that the server only sends data  if  the
              page has changed (default=yes).

       [<URL-SPEC>] validate-with-etag = yes | no
              When  making a conditional request to a server enable the use of
              the HTTP/1.1 cache validator 'Etag' as well as modification time
              'If-Modified-Since'   (default=yes).    The  request-conditional
              option must also be selected for this option to take effect.

       [<URL-SPEC>] try-without-password = yes | no
              If a request is made for a URL  that  contains  a  username  and
              password  then  a  request  is  made  for the same URL without a
              username and password specified (default=yes).  This allows  for
              requests  for the URL without a password to re-direct the client
              to the passworded version.

       [<URL-SPEC>] intr-download-keep = yes | no
              If the client closes the connection while online  the  currently
              downloaded incomplete page should be kept (default=no).

       [<URL-SPEC>] intr-download-size = (integer)
              If the client closes the connection while online the page should
              continue to download if it is  smaller  than  this  size  in  kB
              (default=1).

       [<URL-SPEC>] intr-download-percent = (integer)
              If the client closes the connection while online the page should
              continue to download if it is more than this percentage complete
              (default=80).

       [<URL-SPEC>] timeout-download-keep = yes | no
              If  the  server  connection  times  out  while  reading then the
              currently   downloaded   incomplete   page   should   be    kept
              (default=no).

       [<URL-SPEC>] keep-cache-if-not-found = yes | no
              If  the  remote  server  replies  with  an  error  message  or a
              redirection while there is a cached version with status 200  the
              previously cached version should be kept (default=no).

       [<URL-SPEC>] request-compressed-data = yes | no
              If  the  requests  that  are  made  to the server are to request
              compressed  data  (default=yes).   Requires   zlib   compilation
              option.

       [<URL-SPEC>] request-chunked-data = yes | no
              If  the  requests  that  are  made  to the server are to request
              chunked encoding (default=yes).

OfflineOptions

       Options that control how WWWOFFLE behaves when it is offline.

       [<URL-SPEC>] pragma-no-cache = yes | no
              Whether to request a new copy of a page if the request from  the
              client has 'Pragma: no-cache' (default=yes).  This option should
              be  set  to  'no'  if  when  browsing  offline  all  pages   are
              re-requested by a 'broken' browser.

       [<URL-SPEC>] cache-control-no-cache = yes | no
              Whether  to request a new copy of a page if the request from the
              client has 'Cache-Control: no-cache' (default=yes).  This option
              should  be  set  to  'no' if when browsing offline all pages are
              re-requested by a 'broken' browser.

       [<URL-SPEC>] cache-control-max-age-0 = yes | no
              Whether to request a new copy of a page if the request from  the
              client   has  'Cache-Control:  max-age=0'  (default=yes).   This
              option should be set to 'no' if when browsing offline all  pages
              are re-requested by a 'broken' browser.

       [<URL-SPEC>] confirm-requests = yes | no
              Whether  to return a page requiring user confirmation instead of
              automatically   recording   requests    made    while    offline
              (default=no).

       [<URL-SPEC>] dont-request = yes | no
              Do   not   request   any  URLs  that  match  this  when  offline
              (default=no).

SSLOptions

       Options that control how WWWOFFLE behaves when a connection is made  to
       it  for  an  https or Secure Sockets Layer (SSL) server.  Normally only
       tunnelling (with no decryption or caching of  the  data)  is  possible.
       When  WWWOFFLE  is  compiled  with  the  gnutls  library it is possible
       configure WWWOFFLE to decrypt, cache and re-encrypt the connections.

       quick-key-gen = yes | no
              Normally generation of secret keys for the  SSL/https  functions
              uses  the  default GnuTLS option for random number source.  This
              can be slow on some machines so this option  selects  a  quicker
              but  less  secure random number source (default = no).  Requires
              GnuTLS compilation option.

       expiration-time = (age)
              The length of time after creation  that  each  certificate  will
              expire (default = 1y).  Requires GnuTLS compilation option.

       enable-caching = yes | no
              If caching (involving decryption and re-encryption) of SSL/https
              server connections is allowed (default = no).   Requires  GnuTLS
              compilation option.

       allow-tunnel = (host[:port])
              A  hostname  and port number (a WILDCARD match) for an https/SSL
              server that can be connected to using WWWOFFLE as  a  tunnelling
              proxy  (no  caching  or  decryption  of the data) (default is no
              hosts or ports allowed).  This option should be set to *:443  to
              allow  https to the default port number.  There can be more than
              one option for other ports or hosts as  required.   This  option
              takes precedence over the allow-cache option.  The host value is
              matched against the URL as presented, no hostname to IP or IP to
              hostname  lookups  are  performed to find alternative equivalent
              names.

       disallow-tunnel = (host[:port])
              A hostname and port number (a WILDCARD match) for  an  https/SSL
              server  that  can  not  be  connected  to  using  WWWOFFLE  as a
              tunnelling proxy.  There can be more than one option  for  other
              ports  or  hosts as required.  This option takes precedence over
              the allow-tunnel option.  The host value is matched against  the
              URL  as  presented,  no hostname to IP or IP to hostname lookups
              are performed to find alternative equivalent names.

       allow-cache = (host[:port])
              A hostname and port number (a WILDCARD match) for  an  https/SSL
              server  that  can  be  connected  to using WWWOFFLE as a caching
              proxy (decryption of the data) (default is  no  hosts  or  ports
              allowed).   This option should be set to *:443 to allow https to
              the default port number.  There can be more than one option  for
              other  ports  or  hosts  as required.  The host value is matched
              against the URL as  presented,  no  hostname  to  IP  or  IP  to
              hostname  lookups  are  performed to find alternative equivalent
              names.  Requires GnuTLS compilation option.

       disallow-cache = (host[:port])
              A hostname and port number (a WILDCARD match) for  an  https/SSL
              server  that can not be connected to using WWWOFFLE as a caching
              proxy.   This  option  takes  precedence  over  the  allow-cache
              option.  The host value is matched against the URL as presented,
              no hostname to IP or IP to hostname  lookups  are  performed  to
              find  alternative equivalent names.  Requires GnuTLS compilation
              option.

FetchOptions

       Options that control what linked elements are downloaded when  fetching
       pages that were requested while offline.

LocalHost

       A list of hostnames that the host running the WWWOFFLE  server  may  be
       known by.  This is so that the proxy does not need to contact itself if
       the request has a different name for the same server.

       (host) A hostname or IP address that in connection with the port number
              (in  the  StartUp  section)  specifies  the  WWWOFFLE proxy HTTP
              server.  The hostnames must match exactly, it is not a  WILDCARD
              match.   The  first  named  host  is used as the server name for
              several features so must be a  name  that  will  work  from  any
              client  host on the network.  The entries can be hostnames, IPv4
              addresses or IPv6 addresses enclosed within  '[...]'.   None  of
              the hosts named here are cached or fetched via a proxy.

LocalNet

       A  list  of hostnames whose web servers are always accessible even when
       offline and are not to be cached by WWWOFFLE  because  they  are  on  a
       local network.

       (host) A  hostname or IP address that is always available and is not to
              be cached by WWWOFFLE.  The host name matching uses WILDCARD  s.
              A  host  can  be excluded by appending a '!' to the start of the
              name.  The host value is matched against the URL  as  presented,
              no  hostname  to  IP  or IP to hostname lookups are performed to
              find  alternative  equivalent  names.   The   entries   can   be
              hostnames,  IPv4  addresses  or  IPv6  addresses enclosed within
              '[...]'.  All entries here are assumed to be reachable even when
              offline.  None of the hosts named here are cached or fetched via
              a proxy.

AllowedConnectHosts

       A list of client hostnames that are allowed to connect to the server.

       (host) A hostname or IP address that  is  allowed  to  connect  to  the
              server.   The host name matching uses WILDCARD s.  A host can be
              excluded by appending a '!' to the start of the name.  If the IP
              address  or  hostname  (if  available) of the machine connecting
              matches then it is allowed.  The entries can be hostnames,  IPv4
              addresses or IPv6 addresses enclosed within '[...]'.  All of the
              hosts named in LocalHost are also allowed to connect.

AllowedConnectUsers

       A list of the users that are allowed to connect to the server and their
       passwords.

       (username):(password)
              The  username  and  password  of  the  users that are allowed to
              connect to the server.  If this section is left  empty  then  no
              user authentication is done.  The username and password are both
              stored in plaintext format.  This requires the  use  of  clients
              that handle the HTTP/1.1 proxy authentication standard.

DontCache

       A list of URLs that are not to be cached by WWWOFFLE.

       [!]URL-SPECIFICATION
              Do  not  cache  any URLs that match this.  The URL-SPECIFICATION
              can be negated to allow matches to be cached.  The URLs that are
              not cached will not have requests recorded if offline or fetched
              automatically.

DontGet

       A list of URLs that are not to be got by WWWOFFLE when it  is  fetching
       and not to be served from the WWWOFFLE cache even if they exist.

       [!]URL-SPECIFICATION
              Do  not get any URLs that match this.  The URL-SPECIFICATION can
              be negated to allow matches to be got.

       [<URL-SPEC>] replacement = (URL)
              The  URL  to  use  to  replace   any   URLs   that   match   the
              URL-SPECIFICATION  s instead of using the standard error message
              (default=none).   The  URLs  in  /local/dontget/  are  suggested
              replacements  (e.g. replacement.gif or replacement.png which are
              1x1 pixel transparent images or replacement.js which is an empty
              javascript file).

       <URL-SPEC> get-recursive = yes | no
              Choose  whether  to  get  URLs  that  match  this  when  doing a
              recursive fetch (default=yes).

       <URL-SPEC> location-error = yes | no
              When a URL reply contains a 'Location' header that redirects  to
              a URL that is not got (specified in this section) then the reply
              is modified to be an error message instead  (default=no).   This
              will  stop  ISP proxies from redirecting users to adverts if the
              advert URLs are in this section.

DontCompress

       A list of MIME types and file extensions that are not to be  compressed
       by   WWWOFFLE  (because  they  are  already  compressed  or  not  worth
       compressing).  Requires zlib compilation option.

       mime-type = (mime-type)/(subtype)
              The MIME type of a URL that is not to be compressed in the cache
              (when purging) or when providing pages to clients.

       file-ext = .(file-ext)
              The  file  extension  of  a  URL  that  is  not  to be requested
              compressed from a server.

CensorHeader

       A list of HTTP header lines that are to be removed  from  the  requests
       sent to web servers and the replies that come back from them.

       [<URL-SPEC>] (header) = yes | no | (string)
              A  header field name (e.g. From, Cookie, Set-Cookie, User-Agent)
              and the string to replace the header  value  with  (default=no).
              The  header  is  case  sensitive, and does not have a ':' at the
              end.  The value of "no" means that  the  header  is  unmodified,
              "yes"  or no string can be used to remove the header or a string
              can be used to replace the header.  This only  replaces  headers
              it  finds,  it does not add any new ones.  An option for Referer
              here  will   take   precedence   over   the   referer-self   and
              referer-self-dir options.

       [<URL-SPEC>] referer-self = yes | no
              Sets  the  Referer header to the same as the URL being requested
              (default=no).  This will add  the  Referer  header  if  none  is
              contained in the original request.

       [<URL-SPEC>] referer-self-dir = yes | no
              Sets  the  Referer header to the directory name of the URL being
              requested (default=no).  This will add  the  Referer  header  if
              none  is  contained  in the original request.  This option takes
              precedence over referer-self.

       [<URL-SPEC>] referer-from = yes | no
              Removes the Referer header based on a match of the referring URL
              (default=no).

       [<URL-SPEC>] force-user-agent = yes | no
              Forces a User-Agent header to be inserted into all requests that
              are made by WWWOFFLE (default=no).   This  User-Agent  is  added
              only if there is not an existing User-Agent header and is set to
              the value WWWOFFLE/<version-number>.  This  header  is  inserted
              before  censoring  and  may  be  changed  by  the  normal header
              censoring method.

FTPOptions

       Options to use when fetching files using the ftp protocol.

       anon-username = (string)
              The username to use for anonymous ftp (default=anonymous).

       anon-password = (string)
              The password to use for anonymous ftp (default determined at run
              time).   If  using a firewall then this may contain a value that
              is not valid to the FTP server and may  need  to  be  set  to  a
              different value.

       <URL-SPEC> auth-username = (string)
              The  username  to use on a host instead of the default anonymous
              username.

       <URL-SPEC> auth-password = (string)
              The password to use on a host instead of the  default  anonymous
              password.

MIMETypes

       MIME  Types  to use when serving files that were not fetched using HTTP
       or for files on the built-in web-server.

       default = (mime-type)/(subtype)
              The default MIME type (default=text/plain).

       .(file-ext) = (mime-type)/(subtype)
              The MIME type to associate with a file extension.  The '.'  must
              be  included  in the file extension.  If more than one extension
              matches then the longest one is used.

Proxy

       This contains the names of the HTTP (or other) proxies to use  external
       to the WWWOFFLE server machine.

       [<URL-SPEC>] proxy = (host[:port])
              The hostname and port on it to use as the proxy.

       <URL-SPEC> auth-username = (string)
              The  username to use on a proxy host to authenticate WWWOFFLE to
              it.  The URL-SPEC in this case refers to the proxy and  not  the
              URL being retrieved.

       <URL-SPEC> auth-password = (string)
              The  password to use on a proxy host to authenticate WWWOFFLE to
              it.  The URL-SPEC in this case refers to the proxy and  not  the
              URL being retrieved.

       [<URL-SPEC>] ssl = (host[:port])
              A  proxy  server  that should be used for https or Secure Socket
              Layer (SSL) connections.  Note that for the <URL-SPEC> that only
              the  host  is  checked  and  that  the  other  parts must be '*'
              WILDCARD s.

Alias

       A list of aliases that are used to replace the  server  name  and  path
       with another server name and path.

       URL-SPECIFICATION = URL-SPECIFICATION
              Any requests that match the first URL-SPECIFICATION are replaced
              by the second URL-SPECIFICATION.  The first URL-SPECIFICATION is
              a  wildcard  match for the protocol and host/port, the path must
              match the start of the requested URL exactly  and  includes  all
              subdirectories.

Purge

       The  method to determine which pages to purge, the default age the host
       specific maximum age of the pages in days, and the maximum cache size.

       use-mtime = yes | no
              The method to use to decide which files to  purge,  last  access
              time (atime) or last modification time (mtime) (default=no).

       max-size = (size)
              The maximum size for the cache in MB after purging (default=-1).
              A maximum cache size of -1 (or 0  for  backwards  compatibility)
              means  there  is no limit to the size.  If this and the min-free
              options are both used the smaller cache size  is  chosen.   This
              option  take  into  account  the URLs that are never purged when
              measuring the cache size but will not purge them.

       min-free = (size)
              The minimum amount of  free  disk  space  in  MB  after  purging
              (default=-1).   A  minimum disk free of -1 (or 0) means there is
              no limit to the free space.  If this and  the  max-size  options
              are  both  used  the  smaller cache size is chosen.  This option
              take into account the URLs that are never purged when  measuring
              the cache size but will not purge them.

       use-url = yes | no
              If  true  then use the URL to decide on the purge age, otherwise
              use the protocol and host only (default=no).

       del-dontget = yes | no
              If true then delete the URLs  that  match  the  entries  in  the
              DontGet section (default=no).

       del-dontcache = yes | no
              If  true  then  delete  the  URLs  that match the entries in the
              DontCache section (default=no).

       [<URL-SPEC>] age = (age)
              The  maximum  age  in  the  cache  for  URLs  that  match   this
              (default=14).   An  age of zero means always to delete, negative
              means not to delete.  The  URL-SPECIFICATION  matches  only  the
              protocol  and  host  unless use-url is set to true. Longer times
              can be specified with a 'w', 'm' or 'y' suffix for weeks, months
              or years (e.g. 2w=14).

       [<URL-SPEC>] compress-age = (age)
              The  maximum  age  in  the  cache for URLs that match this to be
              stored uncompressed  (default=-1).   Requires  zlib  compilation
              option.  An age of zero means always to compress, negative means
              never to  compress.   The  URL-SPECIFICATION  matches  only  the
              protocol  and  host  unless use-url is set to true. Longer times
              can be specified with a 'w', 'm' or 'y' suffix for weeks, months
              or years (e.g. 2w=14).

WILDCARD

       A  WILDCARD  match  is one that uses the '*' character to represent any
       group of characters.

       This  is  basically  the  same  as  the  command  line  file   matching
       expressions in DOS or the UNIX shell, except that the '*' can match the
       '/' character.

       For example

       *.gif  matches  foo.gif and bar.gif

       *.foo.com
              matches  www.foo.com and ftp.foo.com

       /foo/* matches  /foo/bar.html and /foo/bar/foobar.html

URL-SPECIFICATION

       When specifying a host  and  protocol  and  pathname  in  many  of  the
       sections  a URL-SPECIFICATION can be used, this is a way of recognising
       a URL.

       For the purposes of this explanation a URL is considered to be made  up
       of five parts.

       proto  The protocol that is used (e.g. 'http', 'ftp')

       host   The server hostname (e.g. 'www.gedanken.demon.co.uk').

       port   The port number on the host (e.g. default of 80 for HTTP).

       path   The  pathname on the host (e.g. '/bar.html') or a directory name
              (e.g. '/foo/').

       args   Optional arguments with the URL used for CGI scripts etc.  (e.g.
              'search=foo').

       For           example          the          WWWOFFLE          homepage:
       http://www.gedanken.demon.co.uk/wwwoffle/ The protocol is  'http',  the
       host  is  'www.gedanken.demon.co.uk',  the port is the default (in this
       case 80), and the pathname is '/wwwoffle/'.

       In         general         this         is          written          as
       (proto)://(host)[:(port)]/[(path)][?(args)]

       Where [] indicates an optional feature, and () indicate a user supplied
       name or number.

       Some example URL-SPECIFICATION options are the following:

       *://*/*
              Any protocol, Any host, Any port, Any path, Any  args  (This  is
              the default for options that can have a <URL-SPEC>

              prefix when none is specified).

       *://*/(path)
              Any protocol, Any host, Any port, Named path, Any args

       *://*/*?
              Any protocol, Any host, Any port, Any path, No args

       *://*/(path)?*
              Any protocol, Any host, Any port, Named path, Any args

       *://(host)
              Any protocol, Named host, Any port, Any path, Any args

       (proto)://*/*
              Named proto, Any host, Any port, Any path, Any args

       (proto)://(host)/*   Named  proto,  Named host, Any port, Any path, Any
       args

       (proto)://(host):/* Named proto, Named host, Default  port,  Any  path,
       Any args

       *://(host):(port)/* Any protocol, Named host, Named port, Any path, Any
       args

       The matching of the host, the  path  and  the  args  use  the  WILDCARD
       matching  that  is  described  above.  The matching of the path has the
       special condition that a WILDCARD of '/*/foo'  will  match  '/foo'  and
       '/any/path/foo', in other words it matches any path prefix.

       In some sections that accept URL-SPECIFICATION s they can be negated by
       inserting the '!'  character  before  it.   This  will  mean  that  the
       comparison  of  a  URL  with  the  URL-SPECIFICATION  will  return  the
       logically opposite value to what would be returned without the '!'.  If
       all  of  the URL-SPECIFICATION s in a section are negated and '*://*/*'
       is added to the end then the sense of the whole section is negated.

       In all sections that accept URL-SPECIFICATION s the comparison  can  be
       made  case insensitive for the path and arguments part by inserting the
       '~' character before it.  (The host and the  protocol  comparisons  are
       always case insensitive).
