Class BusAuthenticationFilter

java.lang.Object

org.overlord.commons.gwt.server.filters.BusAuthenticationFilter

All Implemented Interfaces:

javax.servlet.Filter

public class BusAuthenticationFilter
extends Object
implements javax.servlet.Filter

Filter that is used to protect the Errai bus. This is particularly useful when running in an environment where the Errai app is protected by FORM based auth. FORM based auth sitting in front of the bus will break it. So instead we can exclude the errai bus from authentication and instead protect it with this filter, which must detect whether the user is authenticated and respond with a proper HTTP 401 response code (which can then be processed by the client in some reasonable way).
