+= Node http websocket server =
+
+This is an implementation of the server-side of the WebSocket protocol,
+based on the node http server.
+
+One advantage over other implementations, is that you can still
+server normal HTTP requests over the same port of the WebSocket server.
+
+= About node patches =
+
+The current node HTTP server implementation closes the connection
+after a successful HTTP requests. The patch adds request.connection.hikack()
+to change that behavior in case of WebSocket connections.
+
+To apply the patches, go in the root of your nodejs code, and apply:
+ `patch -P0 < ../path-to/node-http-websocket/patches/*.patch`
+
+
+Cheers,

+= Examples
+
+Make sure to have a patched version of node.
+
+Run socketpolicy.pl as root. This is needed by the flash WebSocket implementation that lookups crossdomain policies on port 843 to ask for connection.
+
+Run `node ping.js` in another console
+
+Open http://localhost:8000/sample.html with Firefox (other browsers not yet tested)
+
+Some times, the page takes long to load (unknown bug). Try reloading.
