All Implemented Interfaces:

javax.servlet.Filter

public class AuthenticationFilter
extends AbstractCasFilter

Filter implementation to intercept all requests and attempt to authenticate the user by redirecting them to CAS (unless the user has a ticket).

This filter allows you to specify the following parameters (at either the context-level or the filter-level):

• casServerLoginUrl - the url to log into CAS, i.e. https://cas.rutgers.edu/login
• renew - true/false on whether to use renew or not.
• gateway - true/false on whether to use gateway or not.

Please see AbstractCasFilter for additional properties.
