Kevin Fogarty at PC World looks at a new HTTP error code proposal:
A high-profile Google developer has proposed that the Internet Engineering Task Force (IETF) that it endorse a new HTTP Status Code to warn readers the page they’re looking for has been censored by authorities, according to TheVerge.
Tim Bray, who co-invented XML and works as Android Developer Advocate at Google, is submitting a proposal that pages censored by someone other than the owner of the site or of the user’s local network display the error code “451 Unavailable for Legal Reasons.”
The number in the code is a reference to Ray Bradbury’s “Farenheit 451,” which describes a dystopian future in which book burnings and the censorship of unacceptable material is routine. Google already highlights search terms that may return censored results, in some countries.
