Phantomjs not rendering Angular + Websockets page
angularjs,websocket,phantomjs,prerender
You would need to compile PhantomJS 2.0 since 1.9.8 does not support websockets. We are running a compiled PhantomJS 2.0 in production for https://prerender.io so you could try just using our production server pointing to a public staging server of yours.

How to wait for WebSocket response in PNaCl

How to improve nodejs / socket io performance?

You can actually improve performance in three ways : 1 - Reduce the size of instructions you send on the socket. You can achieve this by : Minimify your JSON Use MessagePack which is smaller than JSON 2 - Send just what you need. If you need to move the...
If I switch from Javascript polling to websockets, will that reduce server load?
I've implemented a number of push (websocket) and polling mechanisms (HTTP), in my experience if there are multiple client machines all continuously polling the server for status updates and you switch that around so that the server instead fires a status update out to each client when one occurs there...

python - When are WebSocketHandler and TornadoWebSocketClient completely deleted?
python,object,websocket,tornado,deletion
The WebSocket code currently contains some reference cycles, which means that objects are not cleaned up until the next full GC. Even worse, __del__ methods can actually prevent the deletion of an object (in python 3.3 and older: https://docs.python.org/3.3/library/gc.html#gc.garbage), so it's difficult to tell when things are actually getting deleted....
Meteor: Error during WebSocket handshake: Unexpected response code: 400

How to set WebSocket Origin Header from Javascript?

The simple solution would be to simply create an entry in your hosts file to map test.com to 123.123.123.123. You would need to remove this entry later when you want to connect the "real" test.com. A less hacky solution would require the use of a proxy which can re-write your...
