28 | =head1 SYNOPSIS |
29 | |
30 | In your controller: |
31 | |
32 | package MyApp::Controller::Foo; |
33 | |
34 | use parent qw/Catalyst::Controller::CGIBin/; |
35 | |
36 | # example of a forward to /cgi-bin/hlagh/mtfnpy.cgi |
37 | sub dongs : Local Args(0) { |
38 | my ($self, $c) = @_; |
39 | $c->forward($self->cgi_action('hlagh/mtfnpy.cgi')); |
40 | } |
41 | |
42 | In your .conf: |
43 | |
44 | <Controller::Foo> |
45 | <CGI> |
46 | username_field username # used for REMOTE_USER env var |
47 | pass_env PERL5LIB |
48 | pass_env PATH |
49 | pass_env /^MYAPP_/ |
50 | </CGI> |
51 | </Controller::Foo> |
52 | |
53 | =head1 DESCRIPTION |
54 | |
55 | Dispatches to executable CGI files in root/cgi-bin for /cgi-bin/ paths. |
56 | |
57 | A path such as C<root/cgi-bin/hlagh/bar.cgi> will get the private path |
58 | C<foo/CGI_hlagh_bar_cgi>, for controller Foo, with the C</>s converted to C<_>s |
59 | and prepended with C<CGI_>, as well as all non-word characters converted to |
60 | C<_>s. This is because L<Catalyst> action names can't have non-word characters |
61 | in them. |
62 | |
63 | Inherits from L<Catalyst::Controller::WrapCGI>, see the documentation for that |
64 | module for configuration information. |
