HTTP → HTTPS redirect
Port 80 should permanently redirect to the HTTPS URL.
Pass condition in our engine: The HTTP origin redirects to HTTPS (when the probe can connect).
1. Problem description
We send a read-only GET to the http:// host. If it serves content without a 3xx to https, users and some crawlers may stay on HTTP. HSTS does not help the very first visit.
2. Most common causes
- HTTPS works but :80 is a different app.
- The redirect goes to HTTP on another host.
- Port 80 is firewalled so we cannot tell (we report that).
3. How to fix it
- Configure a 301/308 from http:// to https:// on the same host.
- Redirect to the canonical host (www or apex) in one hop if you can.
