@Seirdy We had to rebase the repository to fix some commit messages for a legal reason. Can you rebase this? |
This header accomplishes the following: - Forbids document.write - Forbids document.domain - Forbids use of profiling APIs - Forbids popups (similar to the overly-agressive "sandbox" CSP directive; uplifed from the deprecated Feature-Policy header) These are preffed off in Chromium as "experimental"; the only DP directive currently enabled in Chromium is "force-load-at-top". More information: - Document-Policy explainer: https://github.com/wicg/document-policy/blob/main/document-policy-explainer.md - Document-Policy specification: https://wicg.github.io/document-policy/ - Current directives supported in Chromium: https://chromium.googlesource.com/chromium/src/+/refs/heads/main/third_party/blink/renderer/core/permissions_policy/document_policy_features.json5 To try this out, go to "chrome://flags" and enable experimental web platform features. See implementation status at https://bugs.chromium.org/p/chromium/issues/detail?id=993790.
