Bug 113780 – Extract URL that doesn't inherit a parent's SecurityOrigin out into a constant.

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Mike West]

We're scheduling navigations to 'data:text/html,' in two places in order to end up on a page that doesn't inherit its parent's SecurityOrigin. We should be more explicit about what we're doing.

Mind taking a look, Jochen? Should be pretty much what we discussed (I went with the method, as I didn't see too many occurrences of a bare static string in the codebase).

is the mime type even important at that point?

No idea. I'm not sure what WebKit does with a blank MIME type. I suppose I can test it. I'll do that before landing.

The const here is not needed or helpful. The return type should be just String.

Can we assert isMainThread() here?

Thanks, Alexey and Darin. I'll land this shortly with your tweaks.

The x-frame-options bug got reverted; adjusting this patch to drop that bit. I'll fold it into the other patch once this lands.
