[TYPO3] clear cache from cron script

[Loek Hilgersom]

Hi all,

I need to run a cron job which will update data for an extension in Typo3. After 
updating the data I need to clear the FE-cache for that specific page. How do I 
do that properly?

Is it a matter of just emptying some records in cache_pages
(DELETE FROM cache_pages WHERE id=x)
or is there a more appropriate way to achieve this?

Thanks,
Loek
