CSP: report-to

The Report-To HTTP response header field instructs the user agent to store reporting endpoints for an origin.

Content-Security-Policy: ...; report-to groupname

The directive has no effect in and of itself, but only gains meaning in combination with other directives.

Syntax

Content-Security-Policy: report-to <json-field-value>;
