[TYPO3] TS condition : check whether plugin X is on page

There's nothing on TSREF/userFunc in conditions [1] about caching. As I 
understand this, my userFunction will be called for every request and 
the content rendering caching will be done according to the boolean 
return of my condition. That is, I will possibly have 2 cache records 
for every page. That is not the point. The problem is that my method 
will be called AFAIU for every request, although it depends only on the 
UID of the page, not on an external parameter such as the remote IP 
address or the daytime. That is, once the page has been generated, the 
check is not needed anymore.

Can I somehow prevent these unwanted calls?
