Let's face it: "Cache-busting" is a term we use so much because High Fidelity doesn't respect http rules about caching. So let's fix that with this feature request!

To benefit server operators and clients alike, let us acknowledge and respect http caching headers! If we say a model will last for a week, then respect it! Did our last-modified change? Hey, then sounds like something is needed again! Maybe some ETag goodness! Bottom line, we want better cache control (er, cache-control)!
