Please add a better explanation of why this change is needed, and consider whether more things are needed in the switch statement.

I don't think this is clear enough. Is the issue that the casting operation is returning an incorrect kCFURL* constant? I think you should just say that.

Did this stuff break after the Fetch API changes?

Do you need to do anything to support 'RefreshAnyCacheData'? It might be better to explicitly call out 'ReloadIgnoringCacheData, and DoNotUseAnyCache' before the 'default' just to show that they map to kCFURL*IgnoringCache.

Let's not have a default at all if possible.

After looking into this more closely, it turns out that toPlatformRequestCachePolicy is actually implemented correctly as is. It is just not called in all places where it should. I will update the patch.

Thanks for reviewing!

We usually put ASSERT_NOT_REACHED here instead of a comment.  Some linux compilers also want such a final return statement.
