NAME LWP::UserAgent::CHICaching - LWP::UserAgent with caching based on CHI SYNOPSIS The usual way of using LWP::UserAgent, really, just pass a `cache` parameter with a CHI object to the constructor: my $cache = CHI->new( driver => 'Memory', global => 1 ); my $ua = LWP::UserAgent::CHICaching->new(cache => $cache); my $res1 = $ua->get("http://localhost:3000/?query=DAHUT"); DESCRIPTION This is YA caching user agent. When the client makes a request to the server, sometimes the response should be cached, so that no actual request has to be sent at all, or possibly just a request to validate the cache. HTTP 1.1 defines how to do this. This module makes it possible to use the very flexible CHI module to manage such a cache. But why? Mainly because I wanted to use CHI facilities, and partly because I wanted to focus on HTTP 1.1 features. Attributes and Methods `cache` Used to set the `CHI` object to be used as cache in the constructor. `key`, `clear_key` The key to use for a response. Defaults to the canonical URI of the request. May make sense to set differently in the future, but should probably be left alone for now. `request_uri` The Request-URI of the request. When set, it will clear the `key`, but should probably be left to be used internally for now. `request` Overriding LWP::UserAgent's request method. LIMITATIONS Will only cache `GET` requests and only looks at the `Cache-Control: max-age` header. Does not make any attempts to see if the response is invalid. BUGS Please report any bugs to . TODO This is a very early release, meant just for the author's immediate needs. These are the things that I'd like to do: * Enable smarter generation of keys, so that semantically identical content can be cached efficiently even though they may have different URIs. * Support all of RFC7234 and AUTHOR Kjetil Kjernsmo . ACKNOWLEDGEMENTS It was really nice looking at the code of LWP::UserAgent::WithCache, when I wrote this. COPYRIGHT AND LICENCE This software is copyright (c) 2015 by Kjetil Kjernsmo.
