2xxSuccess · 10
OK
Request succeeded.

3xxRedirection · 8
Multiple Choices
Multiple representations are available; the client may choose.
Moved Permanently

Cosa fa questo strumento
Un riferimento ricercabile per ogni codice di stato HTTP standard, organizzato per classe (1xx informativi, 2xx successo, 3xx redirezione, 4xx errore client, 5xx errore server). Cerca per numero, per nome o per descrizione. Ogni voce include la frase di motivo canonica e l'RFC dove è definita.
Quando usarlo
- Decidere tra
401 Unauthorizede403 Forbiddenper una richiesta rifiutata. - Confermare se un redirect dovrebbe essere
302,303,307o308. - Cercare un codice insolito appena apparso in una riga di log.
- Verificare quale RFC ha introdotto un codice (per esempio,
451 Unavailable For Legal Reasonsè in RFC 7725).
Come funziona
Il dataset è statico e spedito nel bundle della pagina. Non c'è chiamata API — la ricerca gira contro un indice in memoria, quindi è istantanea anche su connessioni lente. I metadati di ogni codice vengono direttamente dal Registry IANA HTTP Status Code e dagli RFC rilevanti (per lo più 9110, con i codici più vecchi che ancora puntano a 7231 e precedenti).
Note
401 vs 403? 401 significa « non hai dimostrato chi sei — riprova con credenziali ». 403 significa « so chi sei e non puoi avere questo ». Se l'utente loggandosi cambierebbe la risposta, restituisci 401; se no, restituisci 403.
302 vs 307? 302 era originariamente pensato per preservare il metodo della richiesta sul redirect, ma la maggior parte dei browser ha storicamente riscritto POST in GET. 303 e 307 sono stati aggiunti per rendere l'intento esplicito: 303 See Other fa sempre GET sul nuovo URL, 307 Temporary Redirect preserva sempre il metodo. Usa 303 dopo un POST riuscito, 307 per un redirect temporaneo che preserva il metodo.
418 I'm a teapot è reale? Sì, ed è ancora in RFC 2324 (1 aprile 1998) e riconosciuto in RFC 9110 §15.5.19. Da usare con parsimonia.
