Hi all, I'm developing an authentication helper (Negotiate/NTLM) for squid and I am trying to understand more how squid handles this process internally. Most of all I'd like to know how and how long squid caches authentication results. I have looked at the debug logs and they show that squid seems to do "less caching" for Negotiate/NTLM than it does for Basic/Digest authentication. I am wondering whether I can do something about this so that a once verified user will only get his credentials re-verified after a certain time and not all during. I am grateful to any insight the list can give me. Thanks in advance! Khaled
