+                # the client and the server.
+                #
+                # Setting a proxy for the https schema in LWP WILL NOT ACCOMPLISH
+                # THIS.
+                #
+                # LWP will connect to the proxy server, and issue a standard GET
+                # request for the target URL, which most proxy servers will refuse
+                # to get.
+                #
+                # The way to use a proxy server is to set some environment variables
+                # and let the underlying Crypt::SSLeay module do the rest.
