=head1 NAME

LWP::UserAgent::CHICaching - LWP::UserAgent with caching based on CHI

=head1 SYNOPSIS

The usual way of using L, really, just pass a C parameter with a L 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");

=head1 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 class simply extends L with L (also in this distribution) which is doing the real work to make it possible to use the very flexible L module to manage such a cache.

But why? Mainly because I wanted to use L facilities, and partly because I wanted to focus on HTTP 1.1 features.

=head1 TODO

This is an early release, but it supports RFC7234 quite well already. Much work remains though. These are the things that I'd like to do:

=over

=item * Enable smarter generation of keys, so that semantically identical content can be cached efficiently even though they may have different URIs. This can be done in a separate role with the current code.

=item * Support all of L<RFC7234|http://tools.ietf.org/html/rfc7234> and L<RFC7232|http://tools.ietf.org/html/rfc7232>
