=head1 METHODS
-=over 4
-
-=item $req->action
-
-Contains the requested action.
+=head2 $req->action
- print $c->request->action;
+[DEPRECATED] Returns the name of the requested action.
-=item $req->address
-Contains the remote address.
+Use C<< $c->action >> instead (which returns a
+L<Catalyst::Action|Catalyst::Action> object).
- print $c->request->address
+=head2 $req->address
-=item $req->args
+Returns the IP address of the client.
-Shortcut for arguments
-
-=item $req->arguments
+=head2 $req->arguments
Returns a reference to an array containing the arguments.
For example, if your action was
- package MyApp::C::Foo;
-
- sub moose : Local {
- ...
- }
+ package MyApp::C::Foo;
+
+ sub moose : Local {
+ ...
+ }
-And the URI for the request was C<http://.../foo/moose/bah> the string C<bah>
+and the URI for the request was C<http://.../foo/moose/bah>, the string C<bah>
would be the first and only argument.
-=item $req->base
+=head2 $req->args
+
+Shortcut for arguments.
+
+=head2 $req->base
Contains the URI base. This will always have a trailing slash.
-If your application was queried with the URI C<http://localhost:3000/some/path>
-then C<base> is C<http://localhost:3000/>.
+If your application was queried with the URI
+C<http://localhost:3000/some/path> then C<base> is C<http://localhost:3000/>.
