 // We handle some special browser-level URLs (like "about:version")
 // before they're handed to a renderer.  This lets us do the URL handling
 // on the browser side (which has access to more information than the
 // renderers do) as well as sidestep the risk of exposing data to
 // random web pages (because from the resource loader's perspective, these
 // URL schemes don't exist).
