=head1 NAME
HTTP::Config - Configuration for request and response objects
=head1 VERSION
version 6.13
=head1 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};
}
=head1 DESCRIPTION
An C<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:
=over 4
=item $conf = HTTP::Config->new
Constructs a new empty C<HTTP::Config> object and returns it.
=item $conf->entries
Returns the list of entries in the configuration object.
In scalar context returns the number of entries.
=item $conf->empty
Return true if there are no entries in the configuration object.
This is just a shorthand for C<< not $conf->entries >>.
=item $conf->add( %matchspec, %other )
=item $conf->add( \%entry )
Adds a new entry to the configuration.
You can either pass separate key/value pairs or a hash reference.
=item $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 configuation object.
=item $conf->matching( $uri, $request, $response )
=item $conf->matching( $uri )
=item $conf->matching( $request )
=item $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 C<undef> in none match.
=item $conf->add_item( $item, %matchspec )
=item $conf->remove_items( %spec )
=item $conf->matching_items( $uri, $request, $response )
Wrappers that hides the entries themselves.
=back
=head2 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.
=over
=item m_scheme => $scheme
Matches if the URI uses the specified scheme; e.g. "http".
=item m_secure => $bool
If $bool is TRUE; matches if the URI uses a secure scheme. If $bool
is FALSE; matches if the URI does not use a secure scheme. An example
of a secure scheme is "https".
=item m_host_port => "$hostname:$port"
Matches if the URI's host_port method return the specified value.
=item m_host => $hostname
Matches if the URI's host method returns the specified value.
=item m_port => $port
Matches if the URI's port method returns the specified value.
=item m_domain => ".$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".
=item m_path => $path
Matches if the URI's path method returns the specified value.
=item m_path_prefix => $path
Matches if the URI's path is the specified path or has the specified
path as prefix.
=item m_path_match => $Regexp
Matches if the regular expression matches the URI's path. Eg. qr/\.html$/.
=item m_method => $method
Matches if the request method matches the specified value. Eg. "GET" or "POST".
=item m_code => $digit
=item 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.
=item m_proxy => $url
Matches if the request is to be sent to the given Proxy server.
=item m_media_type => "*/*"
=item m_media_type => "text/*"
=item m_media_type => "html"
=item m_media_type => "xhtml"
=item 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 $response->content_is_xhtml returns TRUE.
=item m_uri__I<$method> => undef
Matches if the URI object provides the method.
=item m_uri__I<$method> => $string
Matches if the URI's $method method returns the given value.
=item m_header__I<$field> => $string
Matches if either the request or the response have a header $field with the given value.
=item m_response_attr__I<$key> => undef
=item m_response_attr__I<$key> => $string
Matches if the response object has that key, or the entry has the given value.
