[TYPO3] Smart using TYPO3 cache

[Dmitry Martynenko]

Hi list,

I make extension to display information about real estate object in
single view by its code on page "object". Using RealURL it
displayed for example on: http://realt.by/object/123456/

Information about this objects changed frequently - approximately
200-300 new objects added and 1000 altered per day.

If I make my ext as USER, then page cached with content, but by
default TYPO3 cache logic (as I know) I need clear cache for the page
"object" (with all cached contents) when user alter his object to see changes.
And for 1000 altered objects per day I think it is too frequently to
clear all page cache.

I can make ext as USER_INT, but other 8000 object that not changed
today will be not cached!

I want to know, can I clear cache only for specific "page + content",
for example by url or by (page id + parameters)?
