I think you could be able to achieve this with cookie passive persistence 
Otherwise, you can script an iRule that does this, with universal persistence profile

 

when HTTP_REQUEST {
  if {[HTTP::header exists "Your header here"]}{
    if {[HTTP::header "your header here"] ne ""}{ persist add uie [HTTP::header "Your header here"] }
  }
}

 

 

I haven't tested this script, please do before installing

Hi,

Thank-you very much for your quick reply.

One last thing that I want to confirm: the fact the the requests(with same msg id) will come from different api gw nodes(with different IPs)  shouldn't matter right? There is no requirement to have same source ip sending the requests to the LB, the LB should be able to figure out the destination node just by using the msg id from the header?

Thanks!
