[TYPO3-dev] TypoScript: cache_period for USER objects

[Steffen Kamper]

Hi Oliver,

did you looked at the way joey suggested (USER_INT in Extension) ?
I described it in german here: 
http://www.sk-typo3.de/COA_INT-in-Extensions.190.0.html

In my opinion this is the easiest way to have no cached objects in cached 
Extensions.
