Everything about HTTP 451
HTTP status code
In HTTP, HTTP 451 Unavailable For Legal Reasons is a response status code that indicates that a request cannot be satisfied for legal reasons, such as a web page censored by a government. The code value refers to Ray Bradbury's 1953 dystopian novel Fahrenheit 451, in which books are outlawed. 451 provides more information than HTTP 403, which is often used for the same purpose. This status code is currently a proposed standard in RFC 7725, which updated the IANA HTTP Status Codes Registry to include 451. Wikipedia →
