       HTTP server process


       httpd [ -C config-file ] [ -U uses ] [ -T timeout ] [ -D ]
           [ -s ] [ -p ssf ] [ -q ]


       httpd  is  an  HTTP  server. It accepts commands on its standard input and responds on its
       standard output. It MUST be invoked by master(8) with  those  descriptors  attached  to  a
       remote client connection.

       httpd  reads  its  configuration  options  out  of the imapd.conf(5) file unless specified
       otherwise by -C.

       If the directory  <configdirectory>/log/user  exists,  then  httpd  will  create  protocol
       telemetry  logs  for sessions authenticating as user. The telemetry logs will be stored in
       the log/user directory with a filename of the httpd process-id.


       -C config-file
              Use  the  specified  configuration  file  config-file  rather  than   the   default

       -U uses
              The  maximum  number  of  times that the process should be used for new connections
              before shutting down.  The default is 250.

       -T timeout
              The number of seconds that the process  will  wait  for  a  new  connection  before
              shutting  down.   Note  that  a  value  of  0 (zero) will disable the timeout.  The
              default is 60.

       -D     Run external debugger specified in debug_command.

       -s     Serve HTTP over SSL (https).  All data to and from httpd  is  encrypted  using  the
              Secure Sockets Layer.

       -p ssf Tell  httpd  that an external layer exists.  An SSF (security strength factor) of 1
              means an integrity protection layer exists.  Any higher SSF implies  some  form  of
              privacy protection.

       -q     Ignore quotas on DAV appends. This feature was introduced in version 3.0.


       httpd is commonly included in the SERVICES section of cyrus.conf(5) like so:

       SERVICES {
           imap        cmd="imapd -U 30" listen="imap" prefork=0
           imaps       cmd="imapd -s -U 30" listen="imaps" prefork=0 maxchild=100
           lmtpunix    cmd="lmtpd" listen="/var/run/cyrus/socket/lmtp" prefork=0 maxchild=20
           sieve       cmd="timsieved" listen="sieve" prefork=0
           notify      cmd="notifyd" listen="/var/run/cyrus/socket/notify" proto="udp" prefork=1
           httpd       cmd="httpd" listen=8080 prefork=1 maxchild=20


       A  beta  release  of  httpd  was first introduced in the caldav branch of Cyrus in version
       2.4.17, and was included in the mainline releases beginning in version 2.5.0.

       The quota override option, -q, was introduced with Cyrus version 3.0.
