When a downstream ProxySG requests an object that already is cached in an upstream ProxySG, the downstream ProxySG checks the object’s freshness with the origin content server.

When creating policy in the VPM, where can you instruct the ProxySG to enable or disable pipelining of referenced objects?

Log format variable rs(Content-Type) always refers to Content-type header value sent from the proxySG to the client.
