The WebSocket bidirectional high speed communication now is cross-browser compatible.
From jWebSocket v0.8 all the main browsers support communication via the new WebSocket ws:// protocol.
jWebSocket provides FlashBridge and supports ChromeFrame
As of 2010-06-23, Google Chrome 4.0.429+, Safari 5 and Firefox from 3.7a6 natively support WebSockets. Almost all other or older browser versions support Flash by simply installing the Adobe Flash Player plug-in once. This plug-in is used and approved by thousands of websites. Please refer to our Browsers page to see which browsers already have been tested successfully.
Important! To support the jWebSocket FlashBridge you need to open port 843 on your server side firewall or router to process the so called <policy-file-request>. The FlashBridge uses this port for security reasons to check for cross-domain-access. If port 843 is not reachable the FlashBridge provides a fallback to the requested WebSocket port within 3 seconds. jWebSocket supports this Flash feature.
Important! You cannot run the FlashBridge on the file protocol but on http protocol on a web server listening on port 80 only. If you use Tomcat to host your web applications we recommend to either configure Tomcat to listen on port 80 or to use Apache as front end server together with mod_proxy or mod_jk as bridge to Tomcat.
The jWebSocket Server includes a plug-in now that processes this request. Anyway, neither your own server plug-ins nor your client plug-ins are affected by this, it's completely transparent.
