module Rack

# 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:
  # https://github.com/wycats/merb/blob/master/merb-core/lib/merb-core/rack/middleware/conditional_get.rb
