 **Applicability:** Use the Intercepting Filter pattern when
-*  Used when system uses pre-processing or post-processing requests
-* a family of related product objects is designed to be used together, and you need to enforce this constraint
-* you want to provide a class library of products, and you want to reveal just their interfaces, not their implementations
+* a system uses pre-processing or post-processing requests
+* a system should do the authentication/ authorization/ logging or tracking of request and then pass the requests to corresponding handlers 
+* you want a modular approach to configuring pre-processing and post-processing schemes
