I have recently discovered HTML 5's support for the WebSocket protocol. I began idly experimenting with it and I decided to undertake a simple chat program project. For it, I'd like to be able write a WebSocket server and have it serve users inside of a blog post, using Google's Blogger website.
The server would be written in Javascript and would have all the code needed to send one person's "conversation line" to all other WebSocket connections connected to it. Later, I may implement "chatrooms" where each line is simply redirected to certain users.
My first question: would it be possible to create a Javascript-based WebSocket server? I've researched a bit, and it seems that all server implementations were in PHP or some server-side language similar to that. Would it be possible to write a WebSocket server with Javascript?
The server implementation would be inside of a webpage, so as long as the blog is up, the server would work as well. My blog can be found here. The client's code would be like this:
server = "http://imdmstromyf8imdcaptomysl.blogspot.com/post_that_handles_chat";
connection = new WebSocket (server);
The problem is, a WebSocket runs on its own protocol (ws:// or wss://), so changing "http://" to "wss://" would not work. Could I tunnel the WebSocket protocol through HTTP? If I did, I would probably have to use Ajax, but avoiding that is the reason I wanted a WebSocket chat program.
Blogger has a place where you can insert your own HTML; would it be possible to use PHP tags to delineate the code from HTML?
I would just like to know whether it's possible to do what I want, and if it is, some implementation tips or (even better) some example code to use.
