The publication of the Brotli compression method RFC 7932 today seemed like a good opportunity to add one of the missing concepts: HTTP Content Codings.

The list of registered HTTP content codings in the respective IANA registry is relatively short and these values will be added to shortly. More interesting is the question whether there are other values in use that are not properly registered, but still make sense to be added to list of well-known Web Concepts. Any pointers would be greatly appreciated!
