+=head1 NAME
+
+Catalyst::View::Component::SubInclude::ESI - Edge Side Includes (ESI) plugin for C::V::Component::SubInclude
+
+=head1 VERSION
+
+Version 0.02
+
+=cut
+
+our $VERSION = '0.02';
+
+=head1 SYNOPSIS
+
+In your view class:
+
+  package MyApp::View::TT;
+  use Moose;
+
+  extends 'Catalyst::View::TT';
+  with 'Catalyst::View::Component::SubInclude';
+
+  __PACKAGE__->config( subinclude_plugin => 'ESI' );
+
+Then, somewhere in your templates:
+
+  [% subinclude('/my/widget') %]
+
+=head1 DESCRIPTION
+
+C<Catalyst::View::Component::SubInclude::ESI> renders C<subinclude> calls as 
+Edge Side Includes (ESI) include directives. This is a feature implemented by 
+Varnish (L<http://varnish.projects.linpro.no/>) which allows cache-efficient 
+uses of includes.
+
+=head1 CLASS METHODS
+
+=head2 C<generate_subinclude( $c, @args )>
+
+This will roughly translate to the following code:
+
+  my $url = $c->uri_for( @args );
+  return '<!--esi <esi:include src="$url" /> -->';
+
+Notice that the stash will always be empty. This behavior could be configurable
+in the future through an additional switch - for now, this behavior guarantees a
+common interface for plugins.
