+= How to define a URL in the code? =
   * Common patterns live in url_patterns.py
-  * Get parameters are used for things like telling the user that their form was saved correctly
-  * GCI uses Get parameters to determine action in task view.
   * URLs are registered with DjangoUrlPatterns during frontend instantiation
   * See each module’s callback.py module
-  * MapReduces live at some /_ah/mapreduce “special” url.
-  * AppEngine ensures that only app developers can reach those urls.
