Need to create irule that can redirect a port to another port

So your pool member behind the VIP is on port 9080, but it responses with a cookie and redirection to 9080, 9081 or 9082 - is that correct?

 

And the cookie is specific to the port service that the client is redirected to?

 

Or do you have three pool members with one IP and listening on port 9080, 9081 and port 9082?

 

If this is the case, then you use an irule to strip the port out of the pool member responses, and use cookie persistence to ensure that client requests always get sent to back to the same pool member.
