RFC2616 makes for great reading, and the *majority* of it is superbly
thought through. I spent years with a copy close-to-hand at all times.

Concur. However, persistent connections (and possibly pipelining) will
pretty much mean that you'll need to make sure you're maintaining a
priority-queue of textures to fetch. Otherwise it will *feel* slower to
the end-user even if it is actually faster in total fetch-and-render
time. I've been down this road before.
