If OPES is not friendly to caching, I see it as being fatally crippled.

 Please do NOT without further discussion! Application caching is out
 of OPES scope. If we assume HTTP is being adapted, then HTTP already
 has all necessary mechanisms that servers can use to get "all
 requests", even if their responses are cachable. OPES has nothing to
 do with this. We can explicitly say that OPES is not concerned with
 application caching if we want to.
