+The goal of this example is to show you how to use the actix-web client (awc)
+for https related communication.  As of actix-web 2.0.0, one must be very
+careful about setting up https communication.  **You could use the default 
+awc api without configuring ssl but performance will be severely diminished**.
+
+This example downloads a 10MB image from wikipedia.
+
+To run:
+> curl http://localhost:3000 -o image.jpg
