However, a cache in front of a general web server will 1) cause an object miss to have additional latency (though small) and 2) guarantee object hits will be as low as possible.  A cache in front of a dedicated static file server is unnecessary, but worst-case would introduce additional latency only for cache misses.

Agreed.  This is what I was trying to communicate all along.  It was my understanding that this was what the thread was about.

Not sure what you mean here... at my company it's used for everything but proxying (because Apache's process model is contraindicated at high concurrencies if you want to support Keep-Alive connections).  And we serve a lot of traffic at very low latencies.
