 // We use this information in the AlternateNavURLFetcher to avoid displaying
 // infobars for these cases.  Our infobars are designed to allow users to get at
 // intranet sites when they were erroneously taken to a search result page.  In
 // these cases, however, users would be shown a confusing and useless infobar
 // when they really did mean to do a search.
 //
 // Consumers should call RedirectOrigin(), which is guaranteed to synchronously
 // return a value at all times (even during startup or in unittest mode).  If no
 // redirection is in place, the returned GURL will be empty.
