HTTP 202 Accepted vs 431 Request Header Fields Too Large
HTTP 202 (Accepted) is a 2xx Success response, while 431 (Request Header Fields Too Large) is a 4xx Client Error response. 202 indicates that the request has been accepted for processing, but the processing has not been completed. The request might or might not eventually be acted upon. In contrast, 431 means that the server refuses to process the request because an individual header field or all headers collectively are too large.
