Our intranet web app is behaving very strangely. Very often posting back (asp.net) to save form input end in no-action. After a month or so of on-and-off troubleshooting, I finally got around to compare the http request and response headers.
Basically, I have 2 browser sessions, 1 requesting directly to the web server, the other requesting through the load balancer URL. One of the differences between the 2 responses were Date header. The version coming from the LB has a Date header which is 6 minutes in the future. The other difference is Persistent-auth: the LB response is ON, and direct response is OFF.
I am not network admin, so I don't get to poke around. My impression is that http header is emitted by the web server, not the load balancer. Is this even a valid scenario? What should I ask my admin to look for?
