HTTP Status Code 414 signifies URI Too Long. This status is returned when the server refuses to process a request because the length of the URI exceeds the server's limit. A client might encounter this response when the request includes a long query string or overly long URL, which can happen during complex searches or when sending large amounts of data in the URL. In response, clients should consider shortening the URI, possibly by using POST instead of GET to send data in the body rather than the URL.
