+;;; This code is adapted from Ring (http://github.com/mmcgrana/ring).
+;;;
+;;; Required changes from Ring:
+;;;   1. Remove dependencies which use Java classes blacklisted in App Engine.
+;;;   2. Include raw cookie data retrieved using the servlet API. This does not
+;;;      preclude using Ring's cookie middleware, but is required separately:
+;;;      App Engine services do not always use standard-compliant cookies which
+;;;      the Ring middleware parses correctly.
