[sr-dev] where is s proxy_challenge function?

[Juha Heinanen]

jan,

since vars are faster than avps, i defined:

modparam("auth", "challenge_attr", "$var(digest_challenge)")

but it didn't work.  looks like parse_avp_ident function does not
support vars:

 * Parses the following avp indentifier forms:
 *       - "i:<number>"  - old form, deprecated  (e.g. i:42)
 *       - "s:<string>"  - old form, deprecated  (e.g. s:foo)
 *       - "<track>.<name>"                      (e.g.: f.bar)
 *       - "<track>.<name>[<index>]"             (e.g.: f.bar[1])
 *       - "<track><class>.<name>"               (e.g:  tu.bar)
 *       - "<track><class>.<name>[<index>]"      (e.g:  fd.bar[2])
 *       - "<string>"                            (e.g.: foo)

is there something like k vars in s?
