Web Pages And C# Applications

Hey everyone. i have written a simple server that accepts user connections. these connections are made by a simple game which i also made. I would like this game to be played across a network through my server inside of web pages. The thing is the game is 2 player so i want peple to initiate the start of the 2 player game. i.e. via html pages i double click your user name. A message box comes up on your screen challenging you. if you press ok then start the game and make all relevant network connections,otherwise tell me you don't wanna play. How would i go about initialising a "Game Session" thorugh web pages? I have heard that ASP.net ties in very neatly to the framework but i'm lost here. Can scripting control a server application? Has anyone done anything like this before? Any ideas are greatly appreciated. Sailor.
