Hi, Yesterday I deployed a live demo of Zinc-WebSockets http://websocket.stfx.eu Since most proxies and load balancers, most notably Apache, don't handle the WebSocket protocol very well, the only solution is to arrange for direct connections to the Smalltalk image. Deploying and running this code in your own image is pretty easy: ConfigurationOfZincHTTPComponents project latestVersion load: 'WebSocket'. ZnServer startDefaultOn: 1701. ZnWebSocketDelegate installExamplesInDefaultServer. Then open http://localhost:1701/ws-demo with your browser.
