How do I pass the client's IP address to my servers in an HTTP header?

Web applications running behind ZXTM often need to know the client's IP address. By default, ZXTM adds the HTTP header X-Cluster-Client-IP to each HTTP request, but some applications expect to find the client's IP address in a different header, such as X-Forwarded-For. You can add the required header using either RuleBuilder™ or TrafficScript™.

From version ZXTM 4.2 onward, RuleBuilder allows you to use two magic strings "%REMOTE_IP%" and "%REMOTE_PORT%" in RuleBuilder actions, which will be replaced with the remote IP and port respectively when the rule is executed.

The following RuleBuilder rule, for example, sets the client IP address in the X-Forwarded-For header:

In TrafficScript, you would use the following:

http.setHeader("X-Forwarded-For", request.getRemoteIP());
