Hi,
I have a problem using session...
I have a university web site from this site each student login with
his username and password then i create a session variable for him for
tracing student...
there is a problem happened when say registering semester courses if
two web pages opened for two students on the same machine, what
happened is that when one try to register his courses it's registerd
with the user of the second.
what i want to do that when someone login with his user on a machine
and another one try to login on the same machine with a different user
at the same time, it gives him a message that there is a user already
logging in and don't log him on until he closes the second user page.
Hope that what i want to say is clear.
thnx alot
