From 5a51924c2505c1d5616904aa732fdaedd74d3ffe Mon Sep 17 00:00:00 2001

Subject: [PATCH] http: send payload when (proxy) authentication is done
The check that prevents payload from sending in case of authentication
doesn't check properly if the authentication is done or not.
They're cases where the proxy respond "200 OK" before sending
authentication challenge. This change takes care of that.
Fixes #2431
Closes #3669
