Frequently Asked Questions
What are HTTP status codes?
HTTP status codes are 3-digit numbers returned by web servers to indicate the result of a client's request. They tell the browser whether the request was successful, redirected, or encountered an error.
What's the most common status code?
200 OK is the most common—it means the request was successful. 404 Not Found is the most commonly encountered error code.
What's the difference between 301 and 302?
301 is a permanent redirect (the URL has moved forever), while 302 is a temporary redirect (the URL may be available again later). For SEO, 301 passes link equity.
What does 500 Internal Server Error mean?
A 500 error means something went wrong on the server side. It's a generic catch-all error that requires the server administrator to investigate the server logs.
