[squid-users] Delay_pools problem in Squid 3.5.20

Wed Jul 26 01:49:44 UTC 2017

Dear All,

I had installed a squid 3.5.20 on Centos7. I'm also setting up a
delay_pools and cache_peer function on this squid server .

but I don't know why delay_pools function not working now. before I tested
is OK and I can limit user download less then 512 kb. but now, all user
download is over 512kb and can't control. I tried reboot the squid or use
the other delay_pools command to try to test which part has problem to
cause the delay_pools problem. I've checked my config file seem OK (this is
my first time to install and use squid proxy server) , would you mind tell
me is it my config problem or squid bug (maybe)

here is my full config file.
