I would like to limit users from logging in to the website from more than

I have a database that I use to check the username and password of the user,
but I would also like to check if it is the same computer.
How can this be done without using cookies?
if you want to just make sure there aren't concurrent users try using
a hidden form field. Each time the page is sent back verify the
hidden form field matches the data on the server. Each login,
generate a new value for this field. If a user logs in twice (even
from the same computer) you will be able to detect this.
