Hi,
My site works on sessions. Currently when a user logs in, I store all
information in a database table. Whenever the user does something, I
check the database to see if the session is active. If so, I update
the date and time and then update the other tables. If the seesion is
not active, I ask him to enter his password again. A cron job runs
every 30 mins to clean up the inactive sessions.
The problem with this approach is that it puts a huge load on the
database server as for every activity I have to check one table and
based on its value, I perform other operations. What could be a more
effective way of handling this ? I cannot rely on the session file
created when I start a session because if a user closes the browser
window without logging out, I should be able to mark that session as
closed.
Thanks
Pankaj
