We are trying to fix a performance problem.
It is a WSS 3.0 solution running on Windows 2003, behind a hardware load balancer with IE6 clients. We use windows authentication with integrated security.
So far we have found that there appears to be a lot of unnecessary network traffic. There appears to be a pattern with 5 calls that return http 401.2, then 1 call that returns http 401.1, followed by a call that returns http 200.
Anyone know what could be generating these 401.2 errors or why there are 5 of them for each request.
