ICAP service redirect support for tenant systems

You can prevent data loss from your network by employing Internet Content Adaptation Protocol (ICAP) redirect services. You can enable ICAP at the tenant system level, and you can view/clear the ICAP services redirect status and statistics at the tenant systems level. In addition, we've introduced the X-Client-IP, X-Server-IP, X-Authenticated-User, and X-Authenticated-Groups header extensions in an ICAP message to provide information about the source of the encapsulated HTTP message.
