[OpenSIPS-Users] Proxy authentication question

[Bogdan-Andrei Iancu]

Hi Bogdan,

There are 2 transactions - first request without credentials and the 
second one without credentials - and the flags are only transaction 
persistent.

If you really want to perform such a check, you can rely on the fact 
that both requests will have the same Call-ID (or they should, according 
to RFC3261) - so use the local cache (cachedb_local module) with 
cache_store() and cache_fetch() function to check.

Best regards,
