Hello,

You can use the following : 

when HTTP_REQUEST {
  if {[HTTP::header exists X-Forwarded-For]}{
      HTTP::header replace X-Forwarded-For "[HTTP::header X-Forwarded-For], [IP::client_addr]"
  } else {  
      HTTP::header insert X-Forwarded-For [IP::client_addr]
  }
}

Hi Yann, Thanks for the quick response. Will this iRule insert X-Forwarded-For header for the client requests which already have it ?? Looking at the script my understanding is it would check if X-Forwarded-For header exists but cannot understand the replace and insert statements of the script. Can you please shed some light on it. -MSK
