Censorship has a name: 451 Internet sites that are blocked due to government intervention, are now with the marked note “451 unavailable for legal reasons ‘ . So far, Web server issued the code to “403 Forbidden” in such cases. Code 451 to surfers have now explicitly, that content for legal or political reasons have been blocked.
Internet standard is not the HTTP status code 451 officially yet, but he can already be applied. The Internet Engineering Steering Group (IESG), a body involved in the approval of Internet standards, has just approved the new status code.
He should show wide web, which is just 25 years old, in the world, whether blocked content “for legal reasons”, which were censored pages so or removed from the network. It is also intended that a readable text complements the status code and explains who has censored the content on what legal basis. The “blocked by” and “Description” information to identify the instance (legal demand) blocked access due to a legal order.
Code 451 instead code 403
The Web server on which the content is hosted, respond with standardized, three-digit HTTP status codes on the requests of clients – for example from Web browsers. Is the first number of the HTTP-cod
Quite often surfers encounter “403 Forbidden” on the message. It is by default issued by the deploy server if the client does not have permission to access the requested content – for example, because it must re-authenticate itself to do so.
When censored content for legal or political reasons and blocked Web sites, Web pages and server operators so far usually insert code 403. This so the reasoning for the new 451er, underlying censorship but become obscured.
“CODE 451”: Error code 451 pages are marked in the future, do not appear due to government intervention.
The special status code was inspired by the Amazon staff and software developer Tim Bray, who had already submitted a corresponding working paper at the Internet Engineering Task Force (IETF) in 2012 for the first time. The IETF, which is headed by the IESG, especially cares for the standardization of communication protocols used on the Internet and sets the HTTP status codes.
He refers to in his code draft the writer Ray Bradbury, denouncing censorship and State control of information with his novel “Fahrenheit 451”. In the anti-utopia of owning and reading books is prohibited and the fire brigade for responsible to track books and burn. Should you are prevented from the people because to make a free opinion on access to information and reading.
States can disguise intervention
Bray points out, however, that one could not rely on the use of code 451. States or other instances that are denied access to certain information on the Internet, you might want to conceal their intervention itself and therefore prohibit the use of the HTTP status code 451 website operators or providers.
