HTTP 到 HTTPS 重定向

为何重要

If http:// does not redirect to https://, two versions of the site exist and visitors may land on the insecure one.

如何修复

1. Add a permanent 301 redirect from every http:// URL to its https:// version.
2. Enable HSTS once the redirect works everywhere.

使用以下工具检查

• Redirect Generator (.htaccess & Nginx) – Create 301 redirect rules for Apache .htaccess and Nginx, including HTTPS and www.
• Redirect Checker – Trace every hop of a redirect chain with status codes and timings.
