Frequently Asked Questions

401 (Unauthorized) means the request lacks valid authentication credentials — the user needs to log in. 403 (Forbidden) means the server understood the request but refuses to authorize it — the user is authenticated but doesn't have permission.
Use 301 (Moved Permanently) for permanent redirects — browsers and search engines cache this and transfer SEO value. Use 302 (Found/Temporary) when the redirect is temporary and the original URL should still be indexed. Incorrect use of 302 for permanent moves can hurt SEO.
502 occurs when a server acting as a gateway (like Nginx or a load balancer) receives an invalid response from an upstream server. Common causes: upstream server crashed, application errors, memory limits exceeded, or deployment issues.
