accept-types 0.3.0

accept-types helps your application respond to a HTTP request in a way that a client prefers. The Accept header of an HTTP request informs the server which MIME types the client is expecting back from this request, with weighting to indicate the most prefered. If your server can respond in multiple formats (e.g.: JSON, XML, HTML), the client can easily tell your server which is the prefered format without resorting to hacks like ‘&format=json’ on the end of query strings.
