[SR-Users] is_present_hf error on select

[Daniel-Constantin Mierla]

Hello,

the selects were developed by SER guys in the past (when it was a
separate project, 2005-2008), so I am not that familiar with all the
features they support and the actual relation between header names and
select paths. In this case I see that the dash '-' has to be replaced
with underscore '_' in header name, but I guess there can be headers
with underscore in name...

However, if you just want to take the value for header
X-Digium-AppServer-Response-URI, you can use Kamailio's native
pseudo-variable (pv): $hdr(X-Digium-AppServer-Response-URI)

If you need from the second header with same name:
$(hdr(X-Digium-AppServer-Response-URI)[1]) . The index can be an integer
or a PV holding an integer. If the value is negative, it counts from the
end of the list of headers.

Cheers,
Daniel
