module Rack
  ### This middleware provides hooks to certain places in the request /
  # response lifecycle.  This is so that middleware that don't need to filter
  # the response data can safely leave it alone and not have to send messages
  # down the traditional "rack stack".
  #
  # The events are:
  #
  # * on_start(request, response)
  #
  #   This event is sent at the start of the request, before the next
  #   middleware in the chain is called.  This method is called with a request
  #   object, and a response object.  Right now, the response object is always
  #   nil, but in the future it may actually be a real response object.
  #
  # * on_commit(request, response)
  #
  #   The response has been committed.  The application has returned, but the
  #   response has not been sent to the webserver yet.  This method is always
  #   called with a request object and the response object.  The response
  #   object is constructed from the rack triple that the application returned.
  #   Changes may still be made to the response object at this point.
  #
  # * on_send(request, response)
  #
  #   The webserver has started iterating over the response body and presumably
  #   has started sending data over the wire. This method is always called with
  #   a request object and the response object.  The response object is
  #   constructed from the rack triple that the application returned.  Changes
  #   SHOULD NOT be made to the response object as the webserver has already
  #   started sending data.  Any mutations will likely result in an exception.
  #
  # * on_finish(request, response)
  #
  #   The webserver has closed the response, and all data has been written to
  #   the response socket.  The request and response object should both be
  #   read-only at this point.  The body MAY NOT be available on the response
  #   object as it may have been flushed to the socket.
  #
  # * on_error(request, response, error)
  #
  #   An exception has occurred in the application or an `on_commit` event.
  #   This method will get the request, the response (if available) and the
  #   exception that was raised.
  #
  # ## Order
  #
  # `on_start` is called on the handlers in the order that they were passed to
  # the constructor.  `on_commit`, on_send`, `on_finish`, and `on_error` are
  # called in the reverse order.  `on_finish` handlers are called inside an
  # `ensure` block, so they are guaranteed to be called even if something
  # raises an exception.  If something raises an exception in a `on_finish`
  # method, then nothing is guaranteed.
