public class PortFilter
extends AuthorizationFilter

A Filter that requires the request to be on a specific port, and if not, redirects to the same URL on that port.

 /another/path/** = port[8080]

Description copied from class: AccessControlFilter

true if the request should proceed through the filter normally, false if the request should be processed by this filter's AccessControlFilter.onAccessDenied(ServletRequest, ServletResponse, Object) method instead.

Throws:

Exception - if an error occurs during processing.

getScheme

protected String getScheme(String requestScheme,
 int port)

onAccessDenied

protected boolean onAccessDenied(javax.servlet.ServletRequest request,

                          throws IOException

Redirects the request to the same exact incoming URL, but with the port listed in the filter's configuration.

Overrides:
