we have a website that shows the information for the person previously
logged in! The sequence is as follows

Login as user1 and browse the site
logout, shutdown, restart PC
Login as user2 and start browsing site, the results will show the details of
user1. If you hit refresh or ctrl+F5 the info will go back to user2.
however, if you then click any of the links the data changes back to user1,
very odd.

This happens with IE and Firefox.

Is fine if connected without proxy.

proxy.cfg has the following extra config only

[Extra Configuration]

error comes in IE whether http1.1 through proxy is on or off.

I have taken a trace of this problem and the website appears to drop a
session based cookie on the pc.

Has anybody else seen a similar issue?
