Mark, If you use session vars, simply set a session var with a value of UID:PWD. Exampe: SESSION.Tracker = mark:12345
Then, upon login, validate against this. If you have a session var that has the value "mark:12345", then kick them out to a message that tells them that the user is already logged in.

However, the problem is with sharing of usernames and passwords. Say for example I log in as UID = "mark" and PWD = "12345", while I'm in using the site, someone else can use this same user name and password to log in and use the site illegally. The ideal situation would be if I were logged in, then a second person tries to use my UID and PWD, the second person is denied access, and the first person is booted out and given a warning screen that they account may be deactivated because of abuse. I use session management on this site, but have not implemented cookies. What would be a good way to accomplish this? Thanks, Mark ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Archives: http://www.houseoffusion.com/cf_lists/index.cfm?forumid=4 Subscription: http://www.houseoffusion.com/index.cfm?sidebar=lists&body=lists/cf_talk FAQ: http://www.thenetprofits.co.uk/coldfusion/faq Get the mailserver that powers this list at http://www.coolfusion.com
