TYPO3 Core

Sometimes the session times out and you are not prompted to relog into BE (perhaps because you still use it anyway?)

So if session timed out and you clear cache, then the AJAX call does not report that it could not clear cache at all.

This is very inconfortable when debugging an extension and all you have to do is to clear the cache from time to time. I think the BE does not notice that session timed out (because you still use it) but in fact it did and you don't know why you cannot debug your code properly!
