[SR-Users] Replace header value in failure_route

Hello Klaus,

No, removing the header doesn't work either.
Appending it does, but then I get to X-Dispatcher headers. The second one with the correct value.

The regex, or any other way would be nice to have, because I've tried every function in textops and textopsx. The remove functions don't work. Same applies to the subst functions, but I'm assuming I'm doing something wrong there.

Do you need the regex?

Does remove/append_hf work? eg:

append_hf("X-Dispatcher: $(avp(dsattrs){param.value,dispatcher})");
