AJAX and COMET do not peacefully co-exist.

You’ve been warned.

While the COMET iframe is loading, no ajax calls will complete – the ajax calls are blocked by the loading iframe.

Workarounds:

1. Remove ajax from the page
2. have the code that initiates ajax calls suspend the comet and re-initialize it after the ajax is done
3. Change to web sockets – that’s where I’m heading.
