DESCRIPTION

24       An "HTTP::Config" object is a list of entries that can be matched
25       against request or request/response pairs.  Its purpose is to hold
26       configuration data that can be looked up given a request or response
27       object.
28
29       Each configuration entry is a hash.  Some keys specify matching to
30       occur against attributes of request/response objects.  Other keys can
31       be used to hold user data.
32
33       The following methods are provided:
34
35       $conf = HTTP::Config->new
36           Constructs a new empty "HTTP::Config" object and returns it.
37
38       $conf->entries
39           Returns the list of entries in the configuration object.  In scalar
40           context returns the number of entries.
41
42       $conf->empty
43           Return true if there are no entries in the configuration object.
44           This is just a shorthand for "not $conf->entries".
45
46       $conf->add( %matchspec, %other )
47       $conf->add( \%entry )
48           Adds a new entry to the configuration.  You can either pass
49           separate key/value pairs or a hash reference.
50
51       $conf->remove( %spec )
52           Removes (and returns) the entries that have matches for all the
53           key/value pairs in %spec.  If %spec is empty this will match all
54           entries; so it will empty the configuration object.
55
56       $conf->matching( $uri, $request, $response )
57       $conf->matching( $uri )
58       $conf->matching( $request )
59       $conf->matching( $response )
60           Returns the entries that match the given $uri, $request and
61           $response triplet.
62
63           If called with a single $request object then the $uri is obtained
64           by calling its 'uri_canonical' method.  If called with a single
65           $response object, then the request object is obtained by calling
66           its 'request' method; and then the $uri is obtained as if a single
67           $request was provided.
68
69           The entries are returned with the most specific matches first.  In
70           scalar context returns the most specific match or "undef" in none
71           match.
72
73       $conf->add_item( $item, %matchspec )
74       $conf->remove_items( %spec )
75       $conf->matching_items( $uri, $request, $response )
76           Wrappers that hides the entries themselves.
77
78   Matching
79       The following keys on a configuration entry specify matching.  For all
80       of these you can provide an array of values instead of a single value.
81       The entry matches if at least one of the values in the array matches.
82
83       Entries that require match against a response object attribute will
84       never match unless a response object was provided.
85
86       m_scheme => $scheme
87           Matches if the URI uses the specified scheme; e.g. "http".
88
89       m_secure => $bool
90           If $bool is TRUE; matches if the URI uses a secure scheme.  If
91           $bool is FALSE; matches if the URI does not use a secure scheme.
92           An example of a secure scheme is "https".
93
94       m_host_port => "$hostname:$port"
95           Matches if the URI's host_port method return the specified value.
96
97       m_host => $hostname
98           Matches if the URI's host method returns the specified value.
99
100       m_port => $port
101           Matches if the URI's port method returns the specified value.
102
103       m_domain => ".$domain"
104           Matches if the URI's host method return a value that within the
105           given domain.  The hostname "www.example.com" will for instance
106           match the domain ".com".
107
108       m_path => $path
109           Matches if the URI's path method returns the specified value.
110
111       m_path_prefix => $path
112           Matches if the URI's path is the specified path or has the
113           specified path as prefix.
114
115       m_path_match => $Regexp
116           Matches if the regular expression matches the URI's path.  Eg.
117           qr/\.html$/.
118
119       m_method => $method
120           Matches if the request method matches the specified value. Eg.
121           "GET" or "POST".
122
123       m_code => $digit
124       m_code => $status_code
125           Matches if the response status code matches.  If a single digit is
126           specified; matches for all response status codes beginning with
127           that digit.
128
129       m_proxy => $url
130           Matches if the request is to be sent to the given Proxy server.
131
132       m_media_type => "*/*"
133       m_media_type => "text/*"
134       m_media_type => "html"
135       m_media_type => "xhtml"
136       m_media_type => "text/html"
137           Matches if the response media type matches.
138
139           With a value of "html" matches if $response->content_is_html
140           returns TRUE.  With a value of "xhtml" matches if
141           $response->content_is_xhtml returns TRUE.
142
143       m_uri__$method => undef
144           Matches if the URI object provides the method.
145
146       m_uri__$method => $string
147           Matches if the URI's $method method returns the given value.
148
149       m_header__$field => $string
150           Matches if either the request or the response have a header $field
151           with the given value.
152
153       m_response_attr__$key => undef
154       m_response_attr__$key => $string
155           Matches if the response object has that key, or the entry has the
156           given value.
