Web Proxy Forwarding

A Web proxy server intercepts HTTP requ ests and de termines if it has sto red copi es of the reques ted
Web pages. If it does not, the proxy completes the request to the server on the Internet, returning
the requested information to the user and also saving it locally for future requests.
Setting up a Web proxy ser ver o n a ne twor k can be c umber some, bec ause e ach c ompu ter o n the
network must be configured to direct Web requests to the server.
If you have a proxy server on your network, instead of configuring each computer to point to the proxy
server, you can move the server to the WAN and enable Web Proxy Forwarding. The SonicWALL
automatically forwards all Web proxy requests to the proxy server without requiring all the
computers on the network to be configured.
