Does my CDN have a websocket? Where can I find it?
Click the ‘CDN’ tab on the navigation bar, and navigate to 'Multi CDN', then to 'CDN management', and click the settings icon.
Select 'On' under the 'Websocket' section and hit save.
You can find out websocket availability directly on the table to see which CDN supports websocket (‘Available’ means the CDN supports websocket).
If you turn on websocket with the unsupported CDN installed, these CDNs will remain unused.
