[Typo3-dev] Clear Cache

[Lars Houmark]

Hi Bernhard,

Thanks for your reply. Please have a look at my answer to my own post as 
well ;)

I will be looking further into you method, but i also would like to raise a 
suggestion for the cache clear command. When having a plugin with MANY 
records in fx. one sysfolder, it is rather unsmart that it's needed to clear 
the entine cache for that folder (along with the pages for viewing the 
plugin data) just when updating one single record. Figure a scenario where a 
customer is updating their records several times a day, this makes the load 
unnessesary big, because 99% of the records needs to be regenerated, even 
though they haven't changed. A method for passing along another ID for the 
clear cache command, would make it only clear the cache for the records 
implicated in the update.

Am I way off? Anyone see my point?

Regards,

Lars Houmark
