-Engine module thus hiding the details of the particular engine implementation.

=head1 METHODS
-=over 4
+=head2 $req->action
-=item $req->action
+[DEPRECATED] Returns the name of the requested action.
-Contains the requested action.
- print $c->request->action;
+Use C<< $c->action >> instead (which returns a
+L<Catalyst::Action|Catalyst::Action> object).
-=item $req->address
+=head2 $req->address
-Contains the remote address.
+Returns the IP address of the client.
- print $c->request->address
+=head2 $req->arguments
-=item $req->args
+Returns a reference to an array containing the arguments.
-Shortcut for arguments
+ print $c->request->arguments->[0];
-=item $req->arguments
+For example, if your action was
-Returns a reference to an array containing the arguments.
+ package MyApp::C::Foo;
- print $c->request->arguments->[0];
+ sub moose : Local {
+ ...
+ }
-=item $req->base
+and the URI for the request was C<http://.../foo/moose/bah>, the string C<bah>
+would be the first and only argument.
-Contains the url base. This will always have a trailing slash.
+=head2 $req->args
-=item $req->body
+Shortcut for arguments.
-Contains the message body of the request unless Content-Type is
-C<application/x-www-form-urlencoded> or C<multipart/form-data>.
+=head2 $req->base
- print $c->request->body
+Contains the URI base. This will always have a trailing slash.
-=item $req->content_encoding
+If your application was queried with the URI
+C<http://localhost:3000/some/path> then C<base> is C<http://localhost:3000/>.
-Shortcut to $req->headers->content_encoding
+=head2 $req->body

-=item $req->input
+=head2 $req->cookies
-Shortcut for $req->body.
+Returns a reference to a hash containing the cookies.
-=item $req->match
+ print $c->request->cookies->{mycookie}->value;
-This contains be the matching part of a regexp action. otherwise it
-returns the same as 'action'.
+The cookies in the hash are indexed by name, and the values are L<CGI::Cookie>
+objects.
- print $c->request->match;
+=head2 $req->header
-=item $req->method
+Shortcut for $req->headers->header.
-Contains the request method (C<GET>, C<POST>, C<HEAD>, etc).
+=head2 $req->headers
- print $c->request->method;
+Returns an L<HTTP::Headers> object containing the headers for the current request.
-=item $req->param

- $value = $c->request->param('foo');
- @values = $c->request->param('foo');
+Returns the hostname of the client.
+
+=head2 $req->input
+
+Alias for $req->body.
+
+=head2 $req->query_keywords
+
+Contains the keywords portion of a query string, when no '=' signs are
+present.
+
+ http://localhost/path?some+keywords
+
+ $c->request->query_keywords will contain 'some keywords'
+
+=head2 $req->match
+
+This contains the matching part of a Regex action. Otherwise
+it returns the same as 'action', except for default actions,
+which return an empty string.
+
+=head2 $req->method
+
+Contains the request method (C<GET>, C<POST>, C<HEAD>, etc).
+
+=head2 $req->param
+
+Returns GET and POST parameters with a CGI.pm-compatible param method. This
+is an alternative method for accessing parameters in $c->req->parameters.
+
+ $value = $c->request->param( 'foo' );
+ @values = $c->request->param( 'foo' );
@params = $c->request->param;
+Like L<CGI>, and B<unlike> earlier versions of Catalyst, passing multiple
+arguments to this method, like this:
+
+ $c->request->param( 'foo', 'bar', 'gorch', 'quxx' );
+
+will set the parameter C<foo> to the multiple values C<bar>, C<gorch> and
+C<quxx>. Previously this would have added C<bar> as another value to C<foo>
+(creating it if it didn't exist before), and C<quxx> as another value for
+C<gorch>.
