Why don't we like static local AtomicString here?

Should use add instead of set here.

Seems like we should make this one inline.

Seems like we want to make this one inline.

Why are we declaring/defining these? To make sure they aren’t inlined perhaps?

This doesn’t need to be a friend.

Seems like this comment belongs before the class, not in the private section.

Why are we keeping this?

> Source/WebCore/platform/network/ResourceRequestBase.h:37
> +#include <wtf/PassOwnPtr.h>

Why are we adding this?

Should use add instead of set here.

I didn't want to move this since it's going to be replaced with a version that takes an enum.

Same thing here.

Yup.

I want it to be inside the class, so it does need to be a friend.

It broke the WinCairo build:
