This page does not send any request to the OP server. However, it includes markup that tells any OP client that scans it that it consents to being scanned by the server it specifies. This is useful if you’re using a system that doesn’t let you add JavaScript, edit the head of the document, or if you want to make an OP client that indexes pages at its own cadence.
