From 7c83e0f87d7de5c84cddfa7eddfa2d9f653d02b4 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Sergio=20L=C3=B3pez?= Date: Tue, 26 Dec 2017 21:45:08 +0100 Subject: [PATCH] implement support for HTTP proxy (#489) This change allows the user to manually enter an unauthenticated proxy configuration to be used for all API connections.
