Frequently Asked Questions — HTTP Status Code Reference
What are the five categories of HTTP status codes?
1xx codes are informational responses. 2xx codes indicate success, with 200 OK being the most common. 3xx codes are redirections. 4xx codes are client errors like 404 Not Found. 5xx codes are server errors like 500 Internal Server Error.
What is the difference between 301 and 302 redirects?
A 301 is a permanent redirect meaning the resource has moved permanently to a new URL. Search engines transfer link equity to the new URL. A 302 is a temporary redirect meaning the original URL should still be used for future requests.
What does a 403 Forbidden error mean versus a 401 Unauthorized?
A 401 Unauthorized means the request lacks valid authentication credentials and the user should log in. A 403 Forbidden means the server understood the request and the user may be authenticated, but they do not have permission to access the requested resource.
