Very strange then... My best guess is the browser will only accept one 
cookie with a given name in a given set of headers - check the response 
headers to see that they're all there, then you know it's the browser.  
I found the Web Developers Toolbar for Firefox very useful when doing my 
cookie code - you can view, manually add, clear session cookies, clear 
domain cookies, view which cookies will be sent to the server, view 
response headers etc.
