Multiple Login in a single PC should not be possible
in [General]

From: Jagdeep Singh on 14 May 2010 03:18 Hi All! I am looking for a solution, I want a user to do a single Login only on a PC .. E.g. If a User has logged on my website website.com in Internet explorer, then he cant login on same website in another browser like Firefox etc with same loginid or another. Can I trace MAC address of a single machine to solve this issue? Or is there a concept of GLOBAL COOKIE / Cross Browser Cookie which will work for all browsers in a single machine.. I hope You will help me out Regards Jagdeep Singh +91 9988009272

The browser IP address works for us quite reliably. Once logged in, you get a message saying already logged on ... and where ... but it does need a little help if the user closes the browser without logging out. One needs a facility to 'bounce' a user now and again .... however some remote users may well have 'floating' IP addresses :( Cross browser on the same machine may be a little more problematic! How would one know that it's not just from another windows of the same browser. Browser sniffing should allow that to be included, but we've not needed to go that far yet. > Or is there a concept of GLOBAL COOKIE / Cross Browser Cookie which will > work for all browsers in a single machine..

I used to have 2, 1 cable and 1 DSL. I used FreeBSD's PF to do 'load balance' ;) It works really well with any apps that do multiple connections.
