           Product: WebKit

          Platform: Unspecified
        OS/Version: Unspecified

          Priority: P2

Cross-origin resources listed in the CACHE section aren't retrieved with the 'Origin' header and the responses may not contain the 'Access-Control-Allow-Origin' header. This makes it impossible to utilize CORS for appcache resources.

We may need a way to express in the manifest file that the x-origin resource is to be retrieved and cached with the CORS related headers. Maybe a new manifest file section a lot like the CACHE section but a little different... something like...

CACHE-CORS:
http://cross-origin/resource
When fetching, the 'Origin' header would be included and the responses 'Access-Control-Allow-Origin' header would be cached. When accessed by pages associated with the appcache, the access-control-allow-origin header would be provided.
