Chapter 17 HTTP Redirect

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.
