CHAPTER 16 HTTP Redirect 16.1 Overview HTTP redirect forwards the client's HTTP request (except HTTP traffic destined for the UAG) 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. Figure 127 HTTP Redirect Example 16.1.1 What You Can Do in this Chapter Use the HTTP Redirect screens (see Section 16.2 on page 202) to display and edit the HTTP redirect rules. 16.1.2 What You Need to Know Web Proxy Server A proxy server helps client devices make indirect requests to access the Internet or outside network resources/services. A proxy server can act as a firewall or an ALG (application layer gateway) between the private network and the Internet or other networks. It also keeps hackers from knowing internal IP addresses.
