-  # Middleware that enables conditional GET using If-None-Match and
-  # If-Modified-Since. The application should set either or both of the
-  # Last-Modified or Etag response headers according to RFC 2616. When
-  # either of the conditions is met, the response body is set to be zero
-  # length and the response status is set to 304 Not Modified.
-  #
-  # Applications that defer response body generation until the body's each
-  # message is received will avoid response body generation completely when
-  # a conditional GET matches.

-  # Adapted from Michael Klishin's Merb implementation:
