About this HTTP Status Codes
Every HTTP response carries a three-digit status code. This reference lists 30+ of the codes you will actually meet, grouped by family: 1xx informational, 2xx success, 3xx redirects, 4xx client errors and 5xx server errors. Type any code, name or keyword and the table filters as you type.
How to use it
- Start typing in the search box — a code like 404, a name like Redirect, or a word like 'legal'.
- The table filters instantly to matching codes.
- Read the meaning column to decide what to do next.
- Clear the search to see the full list again.
Example
Search 'gateway' and you get 502 Bad Gateway and 504 Gateway Timeout — the two proxy errors that look alike but mean different things.
Frequently asked questions
What is the difference between 401 and 403?
401 means you are not logged in; 403 means you are logged in but still not allowed. Logging in again fixes 401, not 403.
Is 404 my fault or the server's?
Neither, exactly: the URL points to something that isn't there — a deleted page, a dead link or a typo in the address.
