Web Proxy Forwarding

A Web proxy server intercepts HTTP requests and determines if it has stored copies of the
requested 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 server on a network can be cumbersome, because each computer on
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.
