=head1 NAME
=head1 SYNOPSIS
- sub foo :Local :ActionClass('REST') {}
+ sub foo :Local :ActionClass('REST') {
+ ... do setup for HTTP method specific handlers ...
+ }
sub foo_GET {
... do something for GET requests ...
If a method is requested that is not implemented, this action will
return a status 405 (Method Not Found). It will populate the "Allow" header
-with the list of implemented request methods.
+with the list of implemented request methods. You can override this behavior
+by implementing a custom 405 handler like so:
+
+ sub foo_not_implemented {
+ ... handle not implemented methods ...
+ }
+
+If you do not provide an _OPTIONS subroutine, we will automatically respond
+with a 200 OK. The "Allow" header will be populated with the list of
+implemented request methods.
+
+It is likely that you really want to look at L<Catalyst::Controller::REST>,
+which brings this class together with automatic Serialization of requests
+and responses.
-It is likely that you really want to look at L<Catalyst::Controller::REST>.
+When you use this module, the request class will be changed to
+L<Catalyst::Request::REST>.
