I'm testing the circuit breaker software. What I need to do is make sure it will correctly detect various count rates for restful requests. I'd like to have squid recognize a give URI and say drop 1 request out of ten, 2 out of ten, etc, allowing the remaining requests through. Is this approach feasible? From what I've read so far it seems that a filter could be written to do these dropouts. If I'm taking a workable approach do you know where I might find filters that do this or something near it? Or is there something available which might be easier to use?

I have 6 servers all hitting an external server (with firewalls, etc. in between.) This proxy server would be placed just ahead of these 6 servers.
