Internet-Draft 415 June 2012 HTTP/1.1 451 Unavailable For Legal Reasons Content-Type: text/html <html> <head> <title>Unavailable For Legal Reasons</title> </head> <body> <h1>Unavailable For Legal Reasons</h1> <p>This request may not be serviced in the Roman Province of Judea due to Lex3515, the Legem Ne Subversionem Act of AUC755, which disallows access to resources hosted on servers deemed to be operated by the Judean Liberation Front.</p> </body> </html> The use of the 451 status code implies neither the existence nor non- existence of the resource named in the request. That is to say, it is possible that if the legal restriction were removed, a request for the resource might still not succeed. 4 . Security Considerations 4.1 . 451 Unavailable for Legal Reasons 5 .
