[OpenSIPS-Users] local_route & append_hf

[Arsen Semenov]

Hi,

The msg you've catched with trace("htid","t") you see it - as it is in the
buffer, before the changes are applied. The diff (removed or appended
headers) is being applied right before the message goes to wires.
So actually your header should be there.
