Persistent cookies are saved on client's drive, are shared betwen
browser processes - you should try them.
Create a persistent (non-session) cookie called "BowserUniqueId",
with an unique value, if it isnt in current request.
Use a static hashtable to store BrowserUniqueId values as keys, and
HttpSessions as values.
Each time a request came, retrieve the "BrowserUniqueId" cookie from
browser, then retrieve the associated session from the static container,
and if that is a different session than the one returned by the servlet
engine you know one user has opened a new browser process to access
the same servlet, and runs two different sessions.
If there is now session storred under "BrowserUniqueId" key just store the
current one, you know that the user just opened its first browser, and
the "BrowserUniqueId" cookie was remembered from a previous run of
its browser..
However, user can trick you - he can use different browser installations,
or IE and Netscape... You can't force him not to.
