cache bind 去指定的授权bind查询？

sullybear

目前已经配置了cache bind，和授权bind，功能均正常。现在想实现，当cache bind无法对某域名进行解析时，自动去授权bind上查找结果，并缓存。该如何实现呢？
请指教。主要用什么参数？

    晕。。这是DNS cache的根本功能之一。
cache里没有的话，cache会从各级权威server执行迭代查询，最后在这个域的权威server上获取结果。

另外，bind-9.8还支持static-stub的新zone:

BIND now supports a new zone type, static-stub. This allows the
      administrator of a recursive nameserver to force queries for a
      particular zone to go to IP addresses of the administrator's
      choosing, on a per zone basis, both globally or per view. I.e. if
      the administrator wishes to have their recursive server query
      192.0.2.1 and 192.0.2.2 for zone example.com rather than the
      servers listed by the .com gTLDs, they would configure example.com
      as a static-stub zone in their recursive server. [RT #21474]

LZ需要的是递归DNS：

        recursion yes ;

        allow-query-cache { any; };
