Even then the solution is very limited. The OP probably wants to cache all
popular pages/reports, in many cases the same action will be responsible...
a singleton clearly can't address that.

It could be addressed with an object pool that was keyed to actions,
parameters and values and managed by an interceptor. I think it would be
tricky to implement, particularly the promotion of which resources to the
cache and which objects to dispose of.
