Origin Trial Token Deployment

Forthcoming

This article is a placeholder. Only its topic and title are committed at this stage; the substantive body will be drafted in a future cycle of the engine.

The operational pattern for a site operator participating in an origin trial: registering at the Chrome Origin Trials portal, receiving a signed token, and including the token in either the Origin-Trial HTTP response header or the <meta http-equiv="origin-trial"> HTML element. The pattern names token scope (origin-bound versus third-party), token expiration, the common failure mode of deploying a token after the trial has expired, and the third-party token mechanism for JavaScript libraries that enable a trial feature on behalf of their embedders.
