HTTP Redirect
18.1 Overview
HTTP redirect forwards the client’s HTTP request (except HTTP traffic destined for
the ZyWALL) to a web proxy server. In the following example, proxy server A is
connected to the DMZ interface. When a client connected to the LAN1 zone wants
to open a web page, its HTTP request is redirected to proxy server A first. If proxy
server A cannot find the web page in its cache, a policy route allows it to access
the Internet to get them from a server. Proxy server A then forwards the response
to the client.
