+=== Redirection ===
+Remember that the interactive HTML interface is just one way to access the system. Non-interactive interfaces like Synchronization are also common, as are background interactions like AJAX.
+
+Therefore be very wary of using Redirection, which should '''never''' be done in Validators, Onaccept or Onvalidation routines & should be done within REST Controllers only with a check:
+{{{
+def my_resource():
+    """ REST Controller for my_resource """
+
+    def prep(r):
+        if r.representation in shn_interactive_formats
+            redirect ok
+        ...
+}}}
