Hello, according to the guide, changes done on a message while server processing are kept in sip_msg->buf. But if I do something like (in ser.cfg):

[...] append_hf("Anyheader: hello"); showrequest(); [...]

being 'showrequest' a function in a module that just does:

static int showrequest_f(struct sip_msg* msg, char *foo, char *foo2) { parse_headers(msg, HDR_EOH, 0); fprintf(stderr, "MESSAGE:\n"); fprintf(stderr, msg->buf); return 1; }

then I can't see the new header! What am I doing wrong?

Thank you.
