I have the presumption that you two talking of different caching aproaches 
here. It appears to me that you want something like a vignette story-server 
that makes it possible to cache html-pages, and externally control the 
contents and properties (aka lifetime of entries and such things) of it. The 
short answer is: no.

Using the object repository (or any other session/static map based approach) 
makes it possible to create such a facility, but its not implemented yet.

For jsp, there exists a promising approach called oscache. It would be 
possible to rollout a similar mechanism in barracuda, using DOM-Trees and 
BTemplates, but so far its not there. The trickiest part would be generating 
a unique id function, and the lazy execution of data-providing code. 

So far, we have implemented caching based on the data-objects used to fill the 
template-models and thus the html-pages. That resulted in rendering the dom 
every time, but prevented unneccessary db-queries. Actually, that was fast 
enought for us.
