Despite following the exact instructions of this video: [this video] and changing details where necessary (e.g. I am using localhost:8888 as oppose to 3000), I am always getting error messages, no matter what I try. It is becoming extremely frustrating as I can't, for the life of me, figure out where I am going wrong. I am currently getting the error message GET [LINK] 404 (Not Found) after a massive struggle of continuously getting an error where it couldn't locate the 'socket.io.js' file. Can anyone shed some light on this devastatingly cryptic topic?

I developed web site with LAMP, where I need users to chat with each other, make group chat or PM. I googled the solution and found that the best way to create chat/messaging application is NodeJS & SocketIO. I wrote small chat client/server application with Node and Socket. But I have a problem, Node JS runs on another port, because has own server and does not need apache, but my goal is to integrate Chat application with my web site, in short, i want my chat to run with apache 80 port (inside www root folder). I used this tutorial on youtube [this video]

From what I can tell you have the general understanding of how the scripts work, and the overall general concept of what you want to do. Which is good. As far as making your application faster. There's not a whole lot that can be done there with the way it is currently built. The best you can do is look at the speed of any loops you have and check that they are not too in depth as that can overclock processes and decrease the speed at which data is retrieved from the server. JSF Methods I have been researching JSF (JavaServer Faces), which is a J2EE framework for server based applciations. It implements CSS, HTML, and various components of other languages and from what I can tell is extremel
