The Goland draft mentioned below is a ten-year-old proposal.

Rather more useful and general than trying to specify http over UDP is breaking http from TCP as a separate layer, and then putting it over a variety of reliable transports, be they UDP-based, SCTP, TCP or otherwise.

Some notes on this and various pieces of work in this area are at:
http://personal.ee.surrey.ac.uk/Personal/L.Wood/publications/internet-drafts/draft-wood-dtnrg-http-dtn-delivery/lloyd-wood-turning-http-into-a-standalone-layer-ietf-75-tsvarea-slides.pdf
Turning HTTP into a standalone layer: decoupling HTTP from TCP, talk given to the TSVAREA meeting, IETF 75, Stockholm, 27 July 2009.

and on
http://personal.ee.surrey.ac.uk/Personal/L.Wood/dtn/http-dtn

delay-tolerant networking (DTN) provided a motivation for separating HTTP from TCP for environments where TCP fails, but the overall need to treat HTTP as a separate layer remains; just ignore the DTN-forwarding-specific Content- headers.

(meanwhile, Joe Touch would be interested in getting BGP off of only TCP, and onto e.g. SCTP... again, breaking coupling between layers in implementations with greater use of layering. HTTP really is a layer in its own right, and should be able to run over any reliable transport.)
