Question about server app

Hi.
Today I read “M2H Networking Tutorial” and I must say that is very helpful to create my own multiplayer game. But in all examples server and client work in one app. What I must to do to make web multiplayer game and this game all time have one server (irrespective players)?

You can always simply remove all client code from the app…or just remove the server code. However, having both code in one application makes it easier to manage (it can’t hurt anyway).

I believe you should reformulate your question as you are probably looking at solutions for 100+ players with dedicated servers…?

Yes, and I’m looking for sth about create mmo (web player) like WoW - ofc not so extensive.

PS About your anserw - If I remove client code I must open site with game and running server or what ?

Or If it be better I can make desktop client (not web app). Can you give me some tips ?
