Description
It's possible for Web applications to add custom HTTP headers, i.e. for authentication, to resource fetch requests. We have an internal application that is looking to load an authenticated page as a presentation receiver page with a custom header.
The Fetch API does this by allowing the application to pass a Headers object with a Request.
We could make a similar improvement to PresentationRequest to allow passing headers at construction time, or perhaps with start().
This issue is a placeholder for discussion, I can formulate a more complete explainer if there is both internal and external interest in moving forward with this change.
