+    (e.g. "a=1&b=2" vs "b=2&a=1") and produce conflicts unexpecting to users.

+       practical solution is to assume the auth doesn't affect the response.
+    2. Parse the query to avoid the ordering issue. Note that ordering under the
+       same key in the query are NOT cleaned; i.e. "a=1&a=2" and "a=2&a=1" are
+       still considered different.

+       that this drops the "egg=" part historically used to denote the requested
