You can add filter to the IIS, which can process the requests and responses as you like. iis.net/configreference/system.webserver/security/… I dont know if that is such kind of filtering you need? – Angieangil

Answer 1

You may be looking for a DelegatingHandler. These are HTTP Message Handlers that can process the request before it reaches the Controller and can also process the response on the way out of the pipeline. Delegating Handlers can also return the response themselves without calling the rest of the pipeline. You can read about Delegating Handlers here.
