Hi All
I am developing an e-commerce application with
Servlets as thin clients and EJB as the middle tier.
Now my problem is allowing one user to Login to the
application only once, which means that if he/she has
logged in once into the application he can not log in
again from the same m/c or from some different m/c
till he logs out of the application properly.
The point of concern here is how to avoid him from
logging in from Two different m/c. I have been able to
prevent successive log in from the same m/c bu writing
the session id in cookie on the client's browser and
then verifying the session with the session id if he
tries to login again from the same m/c. But i am not
able find any way how i can prevent him from logging
in from two different m/c. I thought about doing this
by using soft database lock (flag in the file) but
that's less efficient and dangerous too.
Does any one have an idea how i can go about doing
this.
Thanks
Niranjan
