Correct me if I'm wrong. IIRC, there isn't a status code for temporary moved *with a timeout. If you use 307, it means the browser will always still check the original apple.com first, then get redirected to apple.com/live. Using 301 would make browser go to apple.com/live directly which improves response time. When the event is finished, they can do a 301 on apple.com/live back to apple.com to overwrite the rule.
