+- By default, if an environment variable C(<protocol>_proxy) is set on
+  the target host, requests will be sent through that proxy. This
+  behaviour can be overridden by setting a variable for this task
+  (see `setting the environment
+  <http://docs.ansible.com/playbooks_environment.html>`_),
+  or by using the C(use_proxy) option.
+- HTTP redirects can redirect from HTTP to HTTPS so you should be sure that
+  your proxy environment for both protocols is correct.
