Hi,
we currently have a strange problem. Some users report problems with our website. As we analyzed the problem, we saw some strange browser behaviors.
This is from our apache log (some parts removed): Browser for all log entries: "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; 3.1)"

As you see, each request is followed by a request to our homepage. As we are routing homepage request to a different application server, the user gets logged out because of a new session id.
It is only reported by a few users but with different browsers. At this moment only IE8.0, IE6.0 and Opera.
Does anybody knows why this strange browser behavior occur?
kind regards Janning
UPDATE: Most users are reporting problems with IE 8, but i have no clue why it sends a homepage request after each successful GET request. Maybe IE wants to show some additional information, looks for a favicon oder company certifcate or whatever.
For most websites this is not a problem of course but it is annoying for us, as the user gets logged out on the homepage for some technical reasons. I know that this is our main problem an di can easily fix it. But i really want to resolve why some IE 8 browsers are requesting the homepage again and again. It can be
- a plugin
- firewall / antivirus / anti-spyware etc.
- IE 8 itself
i don't think its IE8 itself because there are only very few users reporting an issue.
The users are all reporting not to have any plugins installed (most do not know what i am talking about)
It seems somehow reasonable that an anti-spyware tool is doing it. but if users switch to firefox the problem is gone.
i am clueless.
