[TYPO3-english] RealURL: is there an invalidation process for unique aliases?

There is a 'enable404forInvalidAlias' option for cases if alias is given 
but it is not cached. When the alias is cached, RealURL will decode and 
pass cached alias to the rest of the TYPO3. It is a responsibility of the 
corresponding extension (like tt_news) to handle references to non-existing 
records. Extensions may choose to produce a 404 page or a search page or 
redirect to something else. It is beyond ReaURL scope to decide what to do 
in such case.

In my extensions I call $GLOBALS['TSFE']->pageNotFoundAndExit('... does not 
exist.') in such cases.
