[PATCH] Support FTP-over-SSL/TLS for regular FTP
From: Modestas Vainius <hidden>
Date: 2016-06-15 22:55:43
Add a boolean http.sslTry option which allows to enable AUTH SSL/TLS and encrypted data transfers when connecting via regular FTP protocol. Default is false since it might trigger certificate verification errors on misconfigured servers.
