Can Local Connection control HTTP overlap?

Hi all,
This is my first time in this forum.Now I’m facing with a big problem.Pls kindly help me all :frowning:

I have an Web based flash games and what I need to do is “I need to restrict the login browser to make one PC can run one login at a time”.

Let say,While the player is using the games , then if he open another browser and want to play at the same time.The game cannot permit to play the game at the same time on this same pc.

So can I use to control that by using Local Connection?

Thanks in advance.
