Figure 168 HTTP Redirect Example
In the example, proxy server A is connected to ge4 in the DMZ zone. When a client connected
to ge1 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.
To make this example work, make sure you have the following settings.
For HTTP traffic between ge1 and ge4:
• a from LAN to WAN through-ZyWALL rule (default) to allow HTTP request from ge1 to
ge4. Responses to this request are allowed automatically.
• a application patrol rule to allow HTTP traffic between ge1 and ge4.
• a HTTP redirect rule to forward HTTP traffic from ge1 to proxy server A.
For HTTP traffic between ge4 and ge2:
• a from DMZ to WAN through-ZyWALL rule (default) to allow HTTP request from ge4 to
ge2. Responses to this request are allowed automatically.
• a application patrol rule to allow HTTP traffic between ge4 and ge2.
• a policy route to forward HTTP traffic from proxy server A to the Internet.
