LWPx::UserAgent::Cached - Subclass of LWP::UserAgent that caches HTTP GET requests
version 0.008
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/');
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.

LWP::UserAgent
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.
ETag
If-None-Match
no-cache
no-store
Cache-Control
Pragma: no-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.
CHI::Driver::RawMemory
get
set
Read-only accessor that indicates if the current request is cached or not.
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.
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.
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.
Settable at construction or anytime thereafter, indicates whether we should store the HTTP referrer in the cache key. Defaults to false.
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.

300

Parent of this class.
Inspiration for this class.
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.
request_send
response_done
response_header
GET
