For web caching to work the WAN optimization tunnel must allow HTTP (and optionally
HTTPS) traffic. To do this, the WAN optimization rule must include the ports used for
HTTP (and HTTPS) traffic. Set Protocol to HTTP to perform protocol optimization of the
HTTP traffic. You can also enable transparent mode, byte caching, SSL offloading, secure
tunneling, and add an authentication group.
