The Intercepting Filter design patterns provides interception and redirection of requests and response where needed. This pattern is applicable in application security and other rule-based access implementations. Implementing interception filters helps manage such complex scenarios by avoiding the necessity of coding access implementations within individual JSPs. One intercepting filter is implemented to handle all access concerns. Interception filters are usually servlets that implement the Filter servlet interface.

what kind of security ?
where this filter could be used for security ?
is it between view and the controller OR between controller and the model ?
