Name

WWW::Mechanize::Cached - Cache response to be polite

Version

Version 1.32

    $Header: /home/cvs/www-mechanize-cached/Cached.pm,v 1.18 2004/04/12 03:21:25 andy Exp $

Synopsis

    use WWW::Mechanize::Cached;

    my $cacher = WWW::Mechanize::Cached->new;
    $cacher->get( $url );

Description

Uses the Cache::Cache hierarchy to implement a caching Mech. This lets one perform repeated requests without hammering a server impolitely.

Constructor

new

Behaves like, and calls, WWW::Mechanize's new method. Any parms passed in get passed to WWW::Mechanize's constructor.

You can pass in a cache => $cache_object if you want. The $cache_object must have get() and set() methods like the Cache::Cache family.

The cache parm used to be a set of parms that described how the cache object was to be initialized, but I think it makes more sense to have the user initialize the cache however she wants, and then pass it in.

Methods

Most methods are provided by WWW::Mechanize. See that module's documentation for details.

is_cached()

Returns true if the current page is from the cache, or false if not. If it returns undef, then you don't have any current request.

Thanks

Iain Truskett for writing this in the first place.

Oddities

It may sometimes seem as if it's not caching something. And this may well be true. It uses the HTTP request, in string form, as the key to the cache entries, so any minor changes will result in a different key. This is most noticable when following links as WWW::Mechanize adds a Referer header.

Bugs, Requests, Comments

Support for this module is provided via the CPAN RT system:

    http://rt.cpan.org/NoAuth/ReportBug.html?Queue=WWW-Mechanize-Cached

    bug-www-mechanize-cached@rt.cpan.org

This makes it much easier for me to track things and thus means your problem is less likely to be neglected.
