Possible to generate a HTTP request to send to an app on receiving a response from another app?

Hi. I have two servers behind a load balancer and I need a request that comes in for one of them to go to the second one as well. I think this is possible to do using iRules and cloning the request. I'd also like the response that the the first server sends back to the client to be packaged and sent as a request to the second server. I don't care about the body of the response, just the status code, and some headers. Is it possible to have the load balancer, using iRules or some other mechanism create a request with this information and send it over to the second server?

 

Thanks
