**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
