CirrostratusHi Juan,
I believe that all requests would be sent to the pool if there isn't a matching object in RAM cache. I don't see any efficient way around this except adding more links to the trunk on the server side. If you're on v10.x, you might be able to:
check whether the item doesn't exist in cache
track the first request for each object (using the table command)
if the current request isn't the first request going to the pool for that object, use HTTP::collect to hold the HTTP
use the 'after' command to wait x seconds and release the HTTP using HTTP::reelease
I'm skeptical that this can be done. And if it can be done, I'm not sure it will be efficient. It would be a lot simpler to add more links to the trunk.
