Description Daniel Aleksandersen 2017-07-19 14:16:59 UTC 
Hi,

The NetworkManager test endpoint at http://nmcheck.gnome.org/check_network_status.txt needs to be made cache-aware.

Please add `Cache-Control: must-revalidate, max-age=0` HTTP response header to this resource.

This header will ensure clients actually test that their internet connections are working, and not only the connection to their local web accelerator or intermediary caching proxy.

Daniel, I applied the requested change:

curl -iI http://nmcheck.gnome.org

HTTP/1.1 200 OK
Date: Wed, 19 Jul 2017 15:08:19 GMT
Server: Apache/2.2.15 (Red Hat)
Cache-Control: must-revalidate, max-age=0
Connection: close
Content-Type: text/html;charset=UTF-8
Comment 2 Daniel Aleksandersen 2017-07-19 18:48:09 UTC 
Thanks! The test should be more reliable for different network setups now!
