Are pseudo variables sopposed to work in replace() function?
The pseudo variables documentation web page says that they are supported
only by avpops and xlog, but the OpenSER 1.0.0 announcement web page
says that they are supported by textops too...
Who is right?
Thanks.

Looking at the examples I found that AVPs usage is supported at least on
the "replacement" string of subst(), but it appears to me that it isn't
supported in the regular expression.
So, how can I make a regular expression with variable content?
Something like the following:
subst( "/^Proxy-Authorization:.*realm=\"$avp(s:realm)\".*\n//i" );
Thanks.

Hi Federico,
the usage of pseudo-variables inside the regexp was avoided due
performance reasons - all regexp are compiled at startup, they being
only evaluated on runtime.
By having variables into regexp, the compilation of the expression will
must be done each time at runtime :(.
there is only one attempt in this direction - it might help you ; see
the fm operator in avp_check :
http://www.openser.org/docs/modules/1.0.x/avpops.html#AEN325
or
http://www.voice-system.ro/docs/avpops/ar01s06.html#avp_check
regards,
bogdan

What about to implement an "e" regular expressions modifier that make
the regular expression be evaluated every time?

Humm...
I cannot find a way to use it to implement the following.
Do you?
subst( "/^Proxy-Authorization:.*realm=\"$avp(s:realm)\".*\n//i" );
Thanks.

Frederico,
as far as I can see, the subst() you try should remove the Proxy-Auth
hdr, right? why don't you use consume_credential() functions?

bogdan

Because the credential are not used!
I noticed that some UAs send authorization data even when not required
and NOT supposed to send (ACKs, BYEs, etc.).
As I don't want to forward over the credentials, I need a way to remove
then, IF they exists AND are for my realm (and the realm is not known a
priori).
Any solution?
Thanks.

this was not introduced because the regular expressions are pre-compiled

may be an option to allow such case, being admin decision whether to use
