Internet Content Adaption Protocol (ICAP) Fundamentals

Core points on ICAP:

* The Blue Coat AV (virus checking) is an external service which the ProxySG can communicate with using ICAP.
* The policy definition is conducted on the ProxySG using the management console or Content Policy Language.
* There are two modes of operation: RESMOD and REQMOD. In REQMOD the ProxySG intercepts and forwards requests from the client to the origin server for parsing. In RESMOD the ProxySG (ICAP client) intercepts the response from the origin server and uses ICAP to communicate with the external service to process the response message.
