From fb63a0aa3388430545c7857e72251fc52eb85b1c Mon Sep 17 00:00:00 2001 From: Heikki Linnakangas Date: Mon, 3 Jul 2017 14:51:51 +0300 Subject: [PATCH] Treat clean shutdown of an SSL connection same as the non-SSL case. If the client closes an SSL connection, treat it the same as EOF on a non-SSL connection. In particular, don't write a message in the log about that. Michael Paquier.
