iRule parsing errors after upgrading BigIP to 13.1.3 version

Thanks Sachin.

So if I want to use two IP address to be looked at and match in the XFF client field, do you separate with a comma like below?

when HTTP_REQUEST {

set exampleIP "192.0.0.2, 192.0.0.3"  

   HTTP::header insert X-Forwarded-For [IP::addr $exampleIP mask "255.255.255.255"]

  log local0. "Where is exampleIP: [whereis $exampleIP country]"

}
