Daniel,
But the documentation
http://www.kamailio.org/docs/modules/1.5.x/textops.html#id2506229
says that append_hf() can be used inside a reply route?
yes, it can be used. The nuance in the initial question, as I understood, was to add a header to a reply for current processed request. with append_hf you add a header to the current processed sip message (no matter is request or reply).
append_to_reply() adds a header to any eventual reply kamailio may send for the request being processed, not visible in the request if that is forwarded.
Just to give an example, save("location") sends a reply from inside the function. If you want to have a custom header in that reply, that can be done with append_to_reply().
Oh, I see. I did not realise append_hf() always applied to the request context only. Thanks a lot! Learn something new every day.
