   HTTP requests move to HTTPS

   Observed: A request to http://www.model-kartei.de/ was not redirected to HTTPS.

   Why it matters: Visitors who type the address or follow an old link start on unencrypted HTTP. A redirect moves them to the encrypted site before any cookies or form data are sent.

   What to do: Add a permanent (301 or 308) redirect from every http:// URL to the same https:// URL at your CDN, load balancer or web server.

   90% of Forums & Communities peers do this. Limit: Measured for the homepage only, from one location, at the time of the check.
