+# ** Fix upload speed for Cloudflare proxy: from <1MBps to >40MBps **
+# If using cloudflare proxy, replace: 	
+# proxy_set_header   Connection        "Keep-Alive";
+# with:
+# proxy_set_header   Connection        "";
+# and just make sure you also have: proxy_http_version 1.1;
+#
+# Reason: Clears client "Connection" headers so Nginx can manage its own
+# persistent pool via the "upstream" keepalive. Prevents Cloudflare/Client
+# close-signals from killing the backend pipe, drastically boosting speed.
