When ICAP services can be invoked (vectoring point)

At any of following vectoring points in the request path:

Request modification

• NetCache can send the request to the ICAP server before checking its cache for the object.
• If a cache miss occurs, NetCache can send the request to an ICAP server.

Response modification

• After the origin server responds to the request, NetCache sends the request to the ICAP server. This is the only vectoring point for FTP.

• Direct requests for ICAP services
• Control the order of ICAP services
• Control who receives content
