Load balancing multiple sessions from the same source address.

I have a situation where my "front-end", customer-facing server requests data from a "back-end" server, using the AJP13 protocol (TCP 8009), then serves the data back to the customer. During periods of heavy traffic, the "front-end" produces requests for data faster than the "back-end" can answer them. So, I want to load balance my "back-end" servers.

 

 

The problem lies in the fact that all of my traffic comes from the same source IP address, using the same TCP port. So, no load balancing methodology, that uses, IP can be utilized.

 

 

The TCP 8009 packets do have a session ID in the payload of the packet. Each request, has a unique session ID that is present in all of the packets for that request.

 

 

Is it possible to load balance, based on the session ID, and not the source IP adress?

 

 

Thanks!
