What "special processing" apart from what is stated in RFC 1864 do you have in mind ? | To generate the value of the Content-MD5 field, the MD5 | algorithm is computed on the canonical form of the MIME | entity's object. In particular, this means that the | sender applies the MD5 algorithm on the data immediately | after conversion to canonical form, before applying any | content-transfer-encoding, and that the receiver also | applies the MD5 algorithm on the canonical form, after | undoing any content-transfer-encoding. For any questions about which Content-* header fields are relevant for HTTP I'd check the header field registries: http://www.iana.org/assignments/message-headers/perm-headers.html http://www.iana.org/assignments/message-headers/prov-headers.html 2616bis could add a normative reference to RFC 3864, and maybe get rid of long boring lists covered by RFC 4229 (?)
