It can be applied to main document and documents in frames. This is special filter - it will not block matching resource, but only apply HTTP header to pages matching it. Because of this it cannot be mixed with other options speciyfing resource type, like for example `image`, `script` or [`frame`](#frame) (`subdocument`).
