[OpenSER-Users] using remove_hf and append_hf in both route and failure route

[Bogdan-Andrei Iancu]

Hi Mik,

what you added in main route (Request_Route) cannot be removed at all. 
So, the idea is not to add there any hdr that you might want to remove 
later.

If you want to add temporary, use the branch route because the changes 
you do there are per-branch.

regards,
bogdan
