Hello
I would like to ask the list some questions about headers. I've been
reading the list and textops module, but I haven't found how to do this.
Imagine a scenario with 2 SER proxies. The first proxy adds a header
like:
Path: <....>
1 )How can the second proxy add a parameter to this header (and not a
new header)? The result that I'm looking for is something like:
Path: <....>,<....>
2 ) I know that SER can check whether a header is
present(is_present_hf()), but is it possible to extract the information
of a header and use it? I can't use search() function, because I don't
know the information, just the header name. I need to read some
parameters from a header of a SIP message to construct a new header.
You could try subst() from textops (it might be documented only in the
sgml in textops/doc). You have a special escape: \u which will expand to
the message uri, but if you want something else than the uri, you are
out of luck :-)
E.g.:
subst('/^(Path:.*)$/\1,uri=\u');
will add uri=<msg_uri> to your Path header.
