HTTP is stateless.  The only way the server can distinguish different 
clients is by the use of cookies -- which are a stateful hack on top of 
stateless HTTP.

For browsers to implement what you suggest would require a different 
cookie store for different windows or tabs.  I suppose there's no 
*theoretical* obstacle to doing that, but I don't think any browser 
implementer ever actually has.
