Because this (potentially) introduces security implications to
URLRequestRedirectJob (e.g., that it shouldn't be used for arbitrary/hostile
redirects, but only trusted redirects, AIUI), it seems well to add a note here
to that effect.

 class NET_EXPORT URLRequestRedirectJob : public URLRequestJob {
  public:
   // Valid status codes for the redirect job. Other 30x codes are theoretically
   // valid, but unused so far.  Both 302 and 307 are temporary redirects, with
   // the difference being that 302 converts POSTs to GETs and removes upload
   // data.
   enum StatusCode {
     REDIRECT_302_FOUND = 302,
     REDIRECT_307_TEMPORARY_REDIRECT = 307,
   };
 
   // Constructs a job that redirects to the specified URL.  |redirect_reason| is
   // logged for debugging purposes, and must not be an empty string.
