NAME LWPx::UserAgent::Cached - Subclass of LWP::UserAgent that caches HTTP GET requests VERSION version 0.010 SYNOPSIS use LWPx::UserAgent::Cached; use CHI; my $ua = LWPx::UserAgent::Cached->new( cache => CHI->new( driver => 'File', root_dir => '/tmp/cache', expires_in => '1d', ), ); $ua->get('http://www.perl.org/'); DESCRIPTION This module borrows the caching logic from WWW::Mechanize::Cached but without inheriting from WWW::Mechanize; instead it is just a direct subclass of LWP::UserAgent. HTTP/1.1 cache operation Full HTTP/1.1 cache compliance is a work in progress. As of version 0.006 we have limited support for HTTP/1.1 ETag/If-None-Match headers, as well as no-cache and no-store Cache-Control directives (both on request and response) and the Pragma: no-cache request header. ATTRIBUTES cache Settable at construction, defaults to using CHI::Driver::RawMemory with an instance-specific hash datastore and a namespace with the current package name. You can use your own caching object here as long as it has get and set methods. is_cached Read-only accessor that indicates if the current request is cached or not. cache_undef_content_length Settable at construction or anytime thereafter, indicates whether we should cache content even if the HTTP Content-Length header is missing or undefined. Defaults to false. cache_zero_content_length Settable at construction or anytime thereafter, indicates whether we should cache content even if the HTTP Content-Length header is zero. Defaults to false. cache_mismatch_content_length Settable at construction or anytime thereafter, indicates whether we should cache content even if the length of the data does not match the HTTP Content-Length header. Defaults to true. ref_in_cache_key Settable at construction or anytime thereafter, indicates whether we should store the HTTP referrer in the cache key. Defaults to false. positive_cache Settable at construction or anytime thereafter, indicates whether we should only cache positive responses (HTTP response codes from 200 to 300 inclusive) or cache everything. Defaults to true. ignore_headers Settable at construction or anytime thereafter, indicates whether we should ignore Cache-Control: no-cache, Cache-Control: no-store, and Pragma: no-cache HTTP headers when deciding whether to cache a response. Defaults to false. Important note: This option is potentially dangerous, as it ignores the explicit instructions from the server and thus can lead to returning stale content.

HANDLERS This module works by adding request_send, response_done and response_header handlers that run on successful HTTP GET requests. If you need to modify or remove these handlers you may use LWP::UserAgent's handler-related methods.
