451 - Browser extension

451_Logo(PNG) screenshot_451

Project and Goals:

Champions:

Niels ten Oever (ARTICLE 19), dkg (ACLU), Joe Hall (CDT)

Background:

HTTP error code 451 (RFC7725) is an error code to report legal obstacles for serving a webpage. During the hackathon we will focus on implementing and measuring this status code to make censorship more transparent.

Purpose:

As part of ietf99, a browser plugin which would report to the user, and optionally to the webcrawler, cases of HTTP error code 451
