Re: [squid-users] Squid without restrictions and problems withs prezi

Hi,

Thanks for you information. We are using ntlm auth, TCP Denied are ok
in this log? In ou log there are many error TCP Denied 407 and I'm not
sure if this is correct...

About second question, we need to use squid only as reporting tools,
how can we ensure that squid doesn't apply any restriction and deny
any connection? We only use squid to generate statistics with sarg.

Thanks
