FAQ

What is the difference between 401 and 403?

401 means unauthenticated (missing or invalid credentials), 403 means authenticated but not allowed to access.

What does a 5xx error mean?

5xx codes indicate a server-side error, such as 500 (internal error) or 503 (service unavailable).

301 or 302 for a redirect?

Use 301 for a permanent redirect (passes SEO value) and 302 for a temporary one.
