+Suppressing Log Messages
+------------------------
+
+If you're seeing meaningless messages in your logfile, for example `client 
+denied by server configuration: /var/www/data/htaccesstest.txt 
+<https://forum.owncloud.org/viewtopic.php?f=17&t=20217>_`, add this section to 
+your Nginx configuration to suppress them::
+
+         location = /data/htaccesstest.txt {
+            allow all;
+            log_not_found off;
+            access_log off;
+        }
