By default Extbase automatically clears the cache of the current page 
whenever a record has been added/changed/deleted.
If you set the TCEMAIN.clearCacheCmd correctly in your page TS config 
(see [1]) Extbase will clear the affected page(s) even if the records 
are stored in another page (e.g. a SysFolder).
