[TYPO3-mvc] blog_example - caching issues?

[Dan Osipov]

I think smart tagging of pages is the best solution. That way only the 
needed cache is cleared.

Is it up to the developer to decide how to tag pages, or should there be 
some internal method?
For example, if blog_example renders blog with UID 56, it should tag the 
page tx_blogexample_blog_56 - or something like it?
