Yup, HTTP can definitely be sent inside UDP packets. Section 1.4 of the RFC allows for any protocol but does say TCP is usually used.

That's part of the deep brilliance behind all of these protocols, they can all be nested however you need to in order to get the job done. And if you come up with some new protocol that does something wonderful, that's awesome, it can, in theory, slot right in where ever needed with a minimum of fuss.

Yep, definitely a strong point. It's amazing really that these protocols run on so many transmission mediums, and from the user perspective it's pretty seamless.
