Mate, I am not exactly clear what your objective is.
;;;What I need is Each window's ASP session should be different.
What is your reason for this? To take a stab in the dark, does each window replace the previously opened window? (can not have multiple windows open) If this is the reason, you need to give each window a unique name (named in the function that opens the new window) This way each window will be independant of each other and you may open as many as you like simultaneously
Wind is your friend
