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 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 The following methods are provided:
34 $conf = HTTP::Config->new
36 Constructs a new empty "HTTP::Config" object and returns it.
37 $conf->entries
39 Returns the list of entries in the configuration object. In scalar
40 context returns the number of entries.
41 $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 $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 $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 $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 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 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 $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 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 Entries that require match against a response object attribute will
84 never match unless a response object was provided.
85 m_scheme => $scheme
87 Matches if the URI uses the specified scheme; e.g. "http".
88 m_secure => $bool
90 If $bool is TRUE; matches if the URI uses a secure scheme. If
91 $bool is FALSE; matches if the URI does not use a secure scheme.
92 An example of a secure scheme is "https".
93 m_host_port => "$hostname:$port"
95 Matches if the URI's host_port method return the specified value.
96 m_host => $hostname
98 Matches if the URI's host method returns the specified value.
99 m_port => $port
101 Matches if the URI's port method returns the specified value.
102 m_domain => ".$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 m_path => $path
109 Matches if the URI's path method returns the specified value.
110 m_path_prefix => $path
112 Matches if the URI's path is the specified path or has the
113 specified path as prefix.
114 m_path_match => $Regexp
116 Matches if the regular expression matches the URI's path. Eg.
117 qr/\.html$/.
118 m_method => $method
120 Matches if the request method matches the specified value. Eg.
121 "GET" or "POST".
122 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 m_proxy => $url
130 Matches if the request is to be sent to the given Proxy server.
131 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 With a value of "html" matches if $response->content_is_html
140 returns TRUE. With a value of "xhtml" matches if
141 $response->content_is_xhtml returns TRUE.
142 m_uri__$method => undef
144 Matches if the URI object provides the method.
145 m_uri__$method => $string
147 Matches if the URI's $method method returns the given value.
148 m_header__$field => $string
150 Matches if either the request or the response have a header $field
151 with the given value.
152 m_response_attr__$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.
