Hi Arun,

 

 

A few questions about your scenario...

 

 

What is the protocol?

 

 

How do you identify the user ID within the TCP packets?

 

 

Do users share the same TCP connection?

 

 

Do you need a defined pool for each user ID? Or could you just select a destination IP and port based on the user ID?

 

 

You could try collecting the TCP payload using TCP::collect, inspect the payload in CLIENT_DATA and then use the pool command to select a corresponding pool or the node command to select an arbitrary destination IP and port.

 

 

You can get more information on the related events and commands in the iRules wiki:
