Websockets not working in Edge (and IE)


We run an WiseJ 2.0 application on IIS. Using Chrome websockets are used correctly. When we use Edge (or IE) the websockets a protocol switch is requested in the communication but the browser keeps using Get and Post request over HTTPS.

Are Websockets supported in Edge ?

What can cause this behaviour ?

Hi Edwin,

if websockets work fine in Chrome for your application I guess we can exclude a server
problem from our research in that case.

For IE and Edge please check their settings, especially the Compatibility Mode and
the Document Mode. It might be running as a lower IE version not supporting WebSockets.

Hope that helps.

Best regards
