The Servlet container.

No, usually not.

Depends.
Your session could be tied to a cookie, in which case two browsers
probably won't share the session (usually you have separate cookies for
each browser instance, i.e. process, but that depends on the browser).
If you just open another browser window chances are that cookies are
shared between those windows; depends on the browser, though.
Your session could be tied to the URL (i.e., the session ID is part of
the URL), in which case the session would be shared when using the same
URLs, no matter if you're using a different browser, different machine
etc.

Check the servlet spec.

Session could have been invalidated manually.

What exactly do you mean?
Hope this clarified things a bit,
