Questions worth answering upfront.
Type a status code like 404 for its meaning, a single digit like 4 to list a whole class (all 4xx codes), or a keyword like "redirect" to search by name and description.
1xx is informational, 2xx is success, 3xx is redirection, 4xx is a client error (your request), and 5xx is a server error.
No. The status code table is built into the page and the lookup runs entirely in your browser.
