Frequently Asked Questions
What are HTTP status codes?
HTTP status codes are three-digit numbers returned by servers to indicate the result of a client's request. They're grouped into 5 categories (1xx-5xx).
What does 404 mean?
404 Not Found means the server can't find the requested resource. The URL might be wrong, or the resource was deleted or moved.
What's the difference between 301 and 302?
301 is a permanent redirect (use the new URL forever). 302 is a temporary redirect (the original URL might work again later). 301 passes SEO value, 302 doesn't.
What causes 500 errors?
500 Internal Server Error means something went wrong on the server side - a code bug, database issue, or configuration problem. It's not the client's fault.
Are 2xx codes always good?
Yes! All 2xx codes indicate success. 200 (OK) is most common, but 201 (Created), 204 (No Content), and others also mean the request succeeded.
