Implementing the Web SSO Filter

The Web SSO filter is attached to a web application, which is part of a Web SSO. The filter intercepts all HTTP requests. When an unauthenticated HTTP request is recognized, the filter redirects the user to the Web SSO core application. When HTTP request belongs to an authenticated user, the filter does nothing. For filter API details, see package javax.servlet. Also see the source code, for example, src/websso/filter/.
