19.1 Overview

HTTP redirect forwards the client's HTTP request (except HTTP traffic destined for the ISG50) 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.

19.1.2 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.
