problem：ats prefetching does not work!
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!

This feature was removed, partially due to this issue, and because no one used or maintained the code. So unfortunately we will not provide support for this with v6.0.0 and forward.
