Rack convenience middleware to simplify handling of Accept header
env['HTTP_ACCEPT']. Allows ordering of its values (accepted media types)
according to their "quality" (preference level).
This wrapper is typically used to determine the request's prefered media type.
gem install rack-accept-media-types
require 'rack/accept_media_types' env['HTTP_ACCEPT'] #=> 'application/xml;q=0.8,text/html,text/plain;q=0.9' req = Rack::Request.new(env) req.accept_media_types #=> ['text/html', 'text/plain', 'application/xml'] req.accept_media_types.prefered #=> 'text/html'
