HTTP Redirect
13.1 Overview
HTTP redirect forwards the client’s HTTP request (except HTTP traffic destined for the USG) 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.

13.1.2 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 security policy 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.
