+Keyword: RedirectStatus
+Where:   Control
+Type:    Integer
+Desc:    Used in conjunction with the Location redirect syntax, this sets
+         the status code returned. The default is a "302", but can be set
+         to anything in the range 3xx. Valid codes are defined by RFC2616
+         and should be adhered to. This can be useful, for example, to
+         prevent the "duplicate content" penalty imposed by some search 
+         engines.
+
 Keyword: Referer
 Where:   LogFormat
 Desc:    The value of the 'Referer:' header sent by the client. Sometimes
