Intent
Provide pluggable filters to conduct necessary pre-processing and post-processing to requests from a client to a target
Applicability
Use the Intercepting Filter pattern when
- 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
