This is only used by the URLRequestFileJob, right? Can you move the checking of
the NetworkDelegate to URLRequestFileJob? Also, this should be a const member
function.

Done.  I originally missed how to get at the network delegate from the
URLRequestFileJob, or I would have done this before.

 
   // The original url is the url used to initialize the request, and it may
   // differ from the url if the request was redirected.
   const GURL& original_url() const { return url_chain_.front(); }
   // The chain of urls traversed by this request.  If the request had no
   // redirects, this vector will contain one element.
   const std::vector<GURL>& url_chain() const { return url_chain_; }
   const GURL& url() const { return url_chain_.back(); }
 
   // The URL that should be consulted for the third-party cookie blocking
