[SR-Users] How to remove rr param on a reply?

Hi

Is there a way to remove an param from the top most rr header?

I add a rr param towards the B CPE to store some information which is sent back on the rr header of the reply from B.

So far this is what is intended and I also get this param in subsequent route headers from messages created by B and as the route header are remove towards A, this works fine.

Unfortunately, in a case of a reply, the parameter is passed to A which is then sending back the param in the route header which would make it somehow complicated to figure out which side sent that parameter. I'm only interested if sent from B.

So I wonder, is there a way to delete a rr param on replies to make sure I don't get it back in the ACK to the reply?
