My (still under development) website:  
http://passport\_photo\_validator.onthegosystems.com  
causes Explorer to change sessions every call. No matter what I click  
on any page, a new session is generated. When I look at the log, I see  
that every call that’s made from IE gets a new session.

It doesn’t happen on Firefox. Sessions behave normally.

More strange is that it doesn’t happen on neither (Explorer, nor FF)  
on the development machine.

Any suggestions on how I can debug this?

What can I do to start poking around on what the browser needs to get  
from the server in order to continue a session?

Thanks,  
Amir

IE is too stupid to handle URL’s with underscores. Replace with dash (-)  
and your problems will go away. On a related note, if you have two  
different apps one on [example.com](http://example.com) and another on [www.example.com](http://www.example.com) IE will  
fail to produce the right cookie for the [www.example.com](http://www.example.com) site.

Hi Jacob,

That fixed it.

Do you think that IE will work OK for two domains like this:  
[xxx.example.com](http://xxx.example.com)  
[yyy.example.com](http://yyy.example.com)

(but no [example.com](http://example.com))

Thanks,  
Amir

Yes, that should work.

Is it possible that uppercase causes the same problem?
