While that might be useful, it would be much more complicated. In
particular it would complicate what a proxy has to do. (Wouldn't
a proxy cache need to know which URLs are in which 'realm' and
return a suitable SessionID? What SessionID would that be?)

The server is certainly free to change the SessionID if a user moves
into a different 'realm', to use your term.
