HTTP status codes

| Posted in Apache

These are taken from RFC 2616 and verified for Squid. Squid-2 uses almost all codes except 307 (Temporary Redirect), 416 (Request Range Not Satisfiable), and 417 (Expectation Failed). Extra codes include 0 for a result code being unavailable, and 600 to signal an invalid header, a proxy error.

Also, some definitions were added as for RFC 2518 (WebDAV). Yes, there are really two entries for status code 424, compare with http_status in src/enums.h:
