Is there a comprehensive MIME header format reference online somewhere?

Question

I\'ve looked at probably 100 sites, and haven\'t found anything. Some are just lists of mime type values, others references to the RFCs, or more or less direct quotes from them

Answer 1

http://www.iana.org/assignments/media-types/index.html That is the ONLY link you should need!

EDIT: Answer in the Comments

http://ietf.org/rfc all the text is there, but not very useful because there is other stuff too. So then, go to the index: http://ietf.org/rfc/rfc-index and ctrl+f for MIME. This brings up 113 hits. Go through the title until you see what you are looking for, then reference the number and get the full text
