commit 2b1ac1ca1950026fe824c0194d0591579e4dda5b
Author: Nils Goroll <nils.goroll at uplex.de>
Date:   Mon May 18 10:45:59 2015 +0200

    Ref: https://tools.ietf.org/html/rfc7231#section-6.1
    
    Changes:
    
    * 302 Found
    * 307 Temporary Redirect
    
      Do not apply the default ttl, only set a ttl if Cache-Control or Expires are
    present.
      Responses with these status codes are not cacheable by default
    
    * 414 Request-URI Too Large
    
      Cacheable with "heuristic expiration"
