       HTTP::Config - Configuration for request and response objects

VERSION

       version 6.45

SYNOPSIS

        use HTTP::Config;
        my $c = HTTP::Config->new;
        $c->add(m_domain => ".example.com", m_scheme => "http", verbose => 1);

        use HTTP::Request;
        my $request = HTTP::Request->new(GET => "http://www.example.com");

        if (my @m = $c->matching($request)) {
           print "Yadayada\n" if $m[0]->{verbose};
        }

DESCRIPTION

       An "HTTP::Config" object is a list of entries that can be matched against request or
       request/response pairs.  Its purpose is to hold configuration data that can be looked up
       given a request or response object.

       Each configuration entry is a hash.  Some keys specify matching to occur against
       attributes of request/response objects.  Other keys can be used to hold user data.

       The following methods are provided:

       $conf = HTTP::Config->new
           Constructs a new empty "HTTP::Config" object and returns it.

       $conf->entries
           Returns the list of entries in the configuration object.  In scalar context returns
           the number of entries.

       $conf->empty
           Return true if there are no entries in the configuration object.  This is just a
           shorthand for "not $conf->entries".

       $conf->add( %matchspec, %other )
       $conf->add( \%entry )
           Adds a new entry to the configuration.  You can either pass separate key/value pairs
           or a hash reference.

       $conf->remove( %spec )
           Removes (and returns) the entries that have matches for all the key/value pairs in
           %spec.  If %spec is empty this will match all entries; so it will empty the
           configuration object.

       $conf->matching( $uri, $request, $response )
       $conf->matching( $uri )
       $conf->matching( $request )
       $conf->matching( $response )
           Returns the entries that match the given $uri, $request and $response triplet.

           If called with a single $request object then the $uri is obtained by calling its
           'uri_canonical' method.  If called with a single $response object, then the request
           object is obtained by calling its 'request' method; and then the $uri is obtained as
           if a single $request was provided.

           The entries are returned with the most specific matches first.  In scalar context
           returns the most specific match or "undef" in none match.

       $conf->add_item( $item, %matchspec )
       $conf->remove_items( %spec )
       $conf->matching_items( $uri, $request, $response )
           Wrappers that hides the entries themselves.

   Matching
       The following keys on a configuration entry specify matching.  For all of these you can
       provide an array of values instead of a single value.  The entry matches if at least one
       of the values in the array matches.

       Entries that require match against a response object attribute will never match unless a
       response object was provided.

       m_scheme => $scheme
           Matches if the URI uses the specified scheme; e.g. "http".

       m_secure => $bool
           If $bool is TRUE; matches if the URI uses a secure scheme.  If $bool is FALSE; matches
           if the URI does not use a secure scheme.  An example of a secure scheme is "https".

       m_host_port => "$hostname:$port"
           Matches if the URI's host_port method return the specified value.

       m_host => $hostname
           Matches if the URI's host method returns the specified value.

       m_port => $port
           Matches if the URI's port method returns the specified value.

       m_domain => ".$domain"
           Matches if the URI's host method return a value that within the given domain.  The
           hostname "www.example.com" will for instance match the domain ".com".

       m_path => $path
           Matches if the URI's path method returns the specified value.

       m_path_prefix => $path
           Matches if the URI's path is the specified path or has the specified path as prefix.

       m_path_match => $Regexp
           Matches if the regular expression matches the URI's path.  Eg. qr/\.html$/.

       m_method => $method
           Matches if the request method matches the specified value. Eg. "GET" or "POST".

       m_code => $digit
       m_code => $status_code
           Matches if the response status code matches.  If a single digit is specified; matches
           for all response status codes beginning with that digit.

       m_proxy => $url
           Matches if the request is to be sent to the given Proxy server.

       m_media_type => "*/*"
       m_media_type => "text/*"
       m_media_type => "html"
       m_media_type => "xhtml"
       m_media_type => "text/html"
           Matches if the response media type matches.

           With a value of "html" matches if $response->content_is_html returns TRUE.  With a
           value of "xhtml" matches if $response->content_is_xhtml returns TRUE.

       m_uri__$method => undef
           Matches if the URI object provides the method.

       m_uri__$method => $string
           Matches if the URI's $method method returns the given value.

       m_header__$field => $string
           Matches if either the request or the response have a header $field with the given
           value.

       m_response_attr__$key => undef
       m_response_attr__$key => $string
           Matches if the response object has that key, or the entry has the given value.
