16 | |
17 | =head1 SYNOPSIS |
18 | |
19 | In your view class: |
20 | |
21 | package MyApp::View::TT; |
22 | use Moose; |
23 | |
24 | extends 'Catalyst::View::TT'; |
25 | with 'Catalyst::View::Component::SubInclude'; |
26 | |
27 | __PACKAGE__->config( subinclude_plugin => 'ESI' ); |
28 | |
29 | Then, somewhere in your templates: |
30 | |
31 | [% subinclude('/my/widget') %] |
32 | |
33 | =head1 DESCRIPTION |
34 | |
35 | C<Catalyst::View::Component::SubInclude::ESI> renders C<subinclude> calls as |
36 | Edge Side Includes (ESI) include directives. This is a feature implemented by |
37 | Varnish (L<http://varnish.projects.linpro.no/>) which allows cache-efficient |
38 | uses of includes. |

44 | Note that C<$path> should be the private action path - translation to the public |
45 | path is handled internally. After translation, this will roughly translate to |
46 | the following code: |
4e327756 |
47 | |
532f3bcf |
48 | my $url = $c->uri_for( $translated_path, @args )->path_query; |
11a93ea1 |
49 | return '<!--esi <esi:include src="$url" /> -->'; |
4e327756 |
50 | |
51 | Notice that the stash will always be empty. This behavior could be configurable |
52 | in the future through an additional switch - for now, this behavior guarantees a |
53 | common interface for plugins. |
