IPv6 support is not currently provided for this deployment mode. In this deployment mode, IWSVA acts as an ICAP server and accepts ICAP connections from an ICAP v1.0 compliant cache server (acting as a client to IWSVA). Cache servers can help reduce the overall bandwidth requirements and reduce latency by serving cached content locally. IWSVA scans and secure all content returned to the cache server and to the end-user clients.
