RFC 1521, "Multipurpose Internet Mail Extensions, Part One: Mechanisms for Specifying and Describing the Format of Internet Message Bodies," describes the format of MIME bodies. This reference material is useful because HTTP borrows heavily from MIME. In particular, this document is designed to provide facilities to include multiple objects in a single message, to represent body text in character sets other than US-ASCII, to represent formatted multi-font text messages, and to represent nontextual material such as images and audio fragments.
