Abstract:
1. A method for authenticating a request to access a resource, the method comprising: receiving at a servlet the request to access the resource; modifying at least one of the request, a state of the request and information accompanying the request by invoking one or more authentication filters to the request to form a modified request, wherein the invocation of the one or more authentication filters causes an authentication state of a source of the request to be modified such that said source is changed from an unauthenticated status to an authenticated status as a result of the invocation of the one or more authentication filters; determining whether the modified request still requires additional authentication; permitting the modified request to be processed if the modified request does not require additional authentication; applying at least one authentication process to the modified request if the modified request still requires additional authentication; and providing access to a protected resource in response to receiving authentication information.
