NAME
    Cache::Web::Lite - Cache web content somewhere viewable by browsers (
    Lite Version )

SYNOPSIS
      # Define the cache root
      my $cache_root = HTML::Location->new( '/var/www/blah', 'http://ali.as/blah' );
  
      # Create the cache handle
      my $Cache = Cache::Web::Lite->new( cache_root => $cache_root );
  
      # Add a graph to the cache
      $Cache->set( 'my_graph.gif', $graph_data );
  
      # Get the URI to tell a browser where to find it
      my $URI = $Cache->uri( 'my_graph.gif' );

DESCRIPTION
    EXPERIMENTAL AND LARGELY UNTESTED - DO NOT USE THIS MODULE!

    Cache::Web::Lite implements a slimline version of a Cache.pm compatible
    API for caching generated web content in a location where we can
    retrieve it, AND where a browser can get it directly, without having to
    launch another script.

    This is great for generating pages with images in them, as you can use a
    single invocation of a script to generate both the page and any custom
    images for it, and by the time the browser recieves the HTML page, the
    images are in place ready for it to fetch directly from the web server,
    without having to bother the script multiple times.

    Due to it's ::Lite nature, Cache::Web::Lite implements a lookalike API,
    but is not a direct descendant of Cache.pm. See Cache::Web ( if written
    yet ) for a fully compatible and fully feature-complete implementation.

    Cache::Web::Lite also lacks many of the features of Cache.pm. It
    supports only storage and retrieval of raw data and Storable objects.
    Expiry times, load and validation callbacks, and most other extra
    features are not supported.

    For the full Cache.pm API see Cache. Additional properties and methods
    are described below.

PROPERTIES
  new cache_root => HTML::Location
    The constructor takes a series of options in the same form as Cache.pm.
    However, only the cache_root option is supported. Also, unlike Cache.pm,
    the cache_root option MUST be a HTML::Location object which describes
    the path/URI duality of the root of the web cache.

  cache_location
    Unlike "cache_root", which returns the root path of the cache, the
    "cache_location" method returns a copy of the actual HTML::Location
    object for the root of the cache.

SHORTCUT METHODS
  location $key
    Returns a HTML::Location object for the location of the entry, if it
    exists.

  path $key
    Returns the path on the filesystem where the data is stored, if it
    exists.

  uri $key
    Returns a uri string for the web location of the entry, if it exists.

  URI $key
    Returns a URI object for the web location of the entry, if it exists.

TO DO
    * Implement at least a few of the features from Cache.pm

    * Write a more complete test suite.
