From ffd290b4ab247f82722927ba9b21358daa16dbf1 Mon Sep 17 00:00:00 2001 From: Rose <83477269+AtariDreams@users.noreply.github.com> Date: Thu, 1 Jun 2023 11:33:39 -0400 Subject: [PATCH] Log result of httpGetHostname BEFORE closing the connection httpClose frees the memory of con->http. This is problematic because httpGetHostname then tries to access the memory it points to. We have to log the hostname first.
