closing of new browsers

Hi,
I need to implement a feature where i open new browser whenever the user clikcs on any link. When the open browsers count reaches 10 i need to pop up a message to the user saying that the max limit has reached and ask him to close some windows if he wants to open any more new.

whenever i open the windows i set the title as "application name- customer id- customer name".

now on every page i have 2 buttons- close all and close. if the user clicks on close all button all the new broswers have to closed. If he clicks on Close button, all the browsers related to that particular customer have to be closed.

how do i do this. os i am using is windows 2000 prof edition.
i need to do this asp. any help would be appreciated.

thx,
Soujanya
