20 =head1 SYNOPSIS
21
22 In your application class:
23
24   package MyApp;
25
26   use Catalyst qw/
27     ConfigLoader
28     Static::Simple
29     ...
30     SubRequest
31   /;
32
33 In your view class:
34
35   package MyApp::View::TT;
36   use Moose;
37
38   extends 'Catalyst::View::TT';
39   with 'Catalyst::View::Component::SubInclude';
40
41   __PACKAGE__->config( subinclude_plugin => 'SubRequest' );
42
43 Then, somewhere in your templates:
44
45   [% subinclude('/my/widget') %]

47 =head1 DESCRIPTION
48
49 C<Catalyst::View::Component::SubInclude::SubRequest> uses Catalyst sub-requests
50 to render the subinclude contents. 
51
52 It requires L<Catalyst::Plugin::SubRequest>.
53
54 =head1 CLASS METHODS
55
56 =head2 C<generate_subinclude( $c, $path, @args )>
57
58 This will make a sub-request call to the action specified by C<$path>. Note that
59 C<$path> should be the private action path - translation to the public path is
60 handled internally.
61
62 So, after path translation, the call will be (roughly) equivalent to:
63
64   $c->sub_request( $translated_path, {}, @args );
65
66 Notice that the stash will always be empty. This behavior could be configurable
67 in the future through an additional switch - for now, this behavior guarantees a
68 common interface for all plugins.
