We had the idea to use rmi too. We have the problem, that we are not allowed
to use cookies. So we have to make an url rewrite (other ideas ?). We think
that it would
cost a lot of performance to make a call for every request to the session
rmi.

What do you think of a special apache module for adminstration of the
different session ids.

how about running a separate login java instance on one of the boxes which
can be called by all servers over RMI to check login?

Hi,

    Sound a pretty complicated problem. If you don't want to work hard i
have a
not a very good solution. What you can do is Keep the SessionId in the
database.
Apart from id keep track of the time also in the database for session
timeouts.

    Other way i think should be able to communicate with the help of servlet
chaining.
Have a servlet deployed in tomcat. So there will be 4 servlet in 4 tomcats.
This
servlet will check the session table and return either true or false
depending
on the session id present in session table. One servlet will send request to
other four servlet and check if the session id is present in the session
table.
Sound pretty complecated.
