Understanding redirects
Status code 301 means a permanent redirect, 302 and 307 a temporary one, and 308 is the permanent version of 307. The difference matters for search engines: only permanent redirects reliably pass rankings to the new address. Ideally there is a single redirect straight to the final HTTPS address; long chains cost loading time.
Security headers
A few lines of server configuration make many attacks harder: HSTS forces browsers to use HTTPS, a content security policy limits where scripts may be loaded from, and X-Frame-Options prevents other sites from invisibly embedding your page. We show which of these headers are set and which are missing.
Frequently asked questions
Which addresses can I check?
Publicly reachable websites over http and https on the standard ports 80 and 443. For security reasons we do not test internal addresses or other ports.
Why is the page content missing?
We deliberately read only the headers. This keeps the check fast and prevents the tool from being used as a detour for fetching other people’s content.
