problem：ats prefetching does not work!
configuration：
（1）records.config
CONFIG proxy.config.prefetch.prefetch_enabled INT 1
（2）prefetch.config
prefetch_children 192.168.0.0 - 192.168.255.255, 216.1.2.3
（3）squid.log
can not see any information about connections from 127.0.0.1
（4）traffic.out
It seem that ats does not perform tcp communications on prefetching although
prefetch requests are created!
