-// In case of redirect, the behavior is the following:
-// - If in the request |auto_follow_redirects| is true, the interceptor doesn't
-//   have access to any of the intermediate request(s) or response(s).
-//   Otherwise, it has access to intermediate responses as they are sent to the
-//   client and it is also notified when the client asks to follow a redirect.
