Hello,

Try this, irule is simple, you can begin with this and if you need more details or more specification le me now...

when HTTP_REQUEST {

foreach header [HTTP::header names] {

    log local0. "HTTP Header : $header = [HTTP::header values $header]"

    if {$header == "X-Forwarded-For"} {
         in xff it will set the last value of X-Forwarded-For
        set xff "[HTTP::header values $header]"
    }

}
}

Regards
