You can not run simple application socket and node ... I have:
Windows 7 with IIS 7
Error: "NetworkError: 404 Not Found - http://xxx.xxx.xxx.xxx:3001/socket.io/1/?t=1381529854815"
Please your help
Only IIS 8 has Web socket support and only windows 8 can run IIS 8 :-\
However, since you're using node then you should use the socket.io module to do your web socket support. It tries to use web sockets but falls back on server-sent events and long polling if necessary. That means it will work with IIS 7 during development but will use web sockets when you publish it if the host supports them.
