Too bad!
Your workaround works.
I'll use that instead.
Thanks!

This is valid regex according to https://regex101.com/
Any idea's why this won't compile?
Maybe because kamailio uses a regular expression lib that doesn't support this syntax
(since there is a seperate regex module that supports PCRE it implies the
"standard" regexes don't).
Easy work around is to remove all X- headers and add them again, something like:
remove_hf_re("^X-");
if(is_present_hf("X-ThisHeaderShouldNotBeRemoved"))
{
append_hf("X-ThisHeaderShouldNotBeRemoved:
$(hdr(X-ThisHeaderShouldNotBeRemoved))\r\n");
}
