if you are using session.invalidate() it should work unless you are not checking the session on each jsp.
by hitting the back button only the the history of previous screen is displayed, if any operation is tried on the page then the page will return a invalid session and redirect you to a longin page if any.
See if you can delet the history when logging out..then there is no question of going to the previous page

dude i think you are confusing yourself here .... there is no need to write such code in a servlet by hitting back button you are not doing to the servlet unless your form is automatically submitting it self on load

for your currently logged in users declare a static variable in your login servlet ....and increment it evertime anyone accesses it....and in logout decrement it..

A more polished way of doing the same thing is if you are using Struts then in the Action servlet you can do this check if a session object is null or not, so you dont have to include anytihng in your JSPs, since all the requests go through this servlet
If anyone knows better approaches please let us know, since this is soething every web developer comes across
