Something I implemented....
Requirement : I have multiple servlets on my site, each doing a specific
job, then rendering a page and then redirecting the user to the other
servlet, depending on links the user clicks.
To maintain a session as such for the above
1. I have "my" SessionManager class which creates and gives a unique session
id to the user when he logs in...
This I presently store in the HttpSession Object of the response, hence for
every request I get a sessionID from the HttpSessionObject. Mind you this is
a sepearate session id than the one you get from the HttpSession getId.
2. Simultaneously I maintain the id in "my" SessionManager Object with other
relevant information, and a thread keeps running to remove the ids after a
specific time - Session Logout.
3. For every request I verify/validate the user, depending on his id with
the one with the SessionManager.
Note : this works for browsers accepting and setting cookies.
The remedy to support all browsers would be to use urlEncode method to
encode the urls.
Performance-wise I think this is a better option for a small number of
users, or else the SessionManager object could cause a bottleneck for a
large number of ideas.
Hope it helps,
Yogesh
