            Bug ID: 185070
           Summary: CSP: Implement `prefetch-src` directive
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebCore Misc.
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: yoav at yoav.ws

In order to block potential data leaks through prefetch requests, it was decided [1] that a `prefetch-src`CSP directive would be added and control such requests, and that prefetch requests would have their own `Request.initiator` and an empty string destination[2].
