HTTP::Config(3) Configuration for request and response objects


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

use HTTP::Request;
my $request = HTTP::Request->new(GET => "");

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


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.
Returns the list of entries in the configuration object. In scalar context returns the number of entries.
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 configuation 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.


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 ``'' 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.
