[cisco-voip] UCCX 11.0.1 bug watch

[Anthony Holloway]

If I know what you are referring to, about my earlier post, this has to do
with using a browser which does not support the type of LiveData feed that
Cisco intends for you to use.

LiveData functions best when the browser supports HTTP WebSockets
<https://en.wikipedia.org/wiki/WebSocket>.  This is a method of
opening/closing fewer HTTP connections from clients to server and passing
multiple data updates over a single connection.

When you use an older browser (E.g., IE 9), OR you use a newer browser in
older compatibility view mode (E.g., IE 11 compatible mode) the Livedata
implementation in Finesse doesn't fail, it actually gracefully degrades to
basic HTTP GET requests and passes every single update to the live data
views over individual connections.  This cause a significant increase of
load on the SocketIO process and the CPU will go through the roof.

As far as I know, this is not a documented defect, because the
compatibility matrix specifically states which browsers are supported.  So
in theory, you shouldn't be using a browser that causes this issue in the
first place.
