Re: [squid-users] Ignoring query string from url

Does these Redirector statistics mean url rewrite helper program is
slowing down squid response ? avg service time is 1550 msec.

Redirector Statistics:
program: /home/zdn/bin/redirect_parallel.pl
number running: 2 of 2
requests sent: 1069753
replies received: 1069752
queue length: 0
avg service time: 1550 msec

# FD PID # Requests Flags Time Offset Request
1 10 18237 12645 B 0.002 38 (none)
2 15 18238 12335 2.144 0 (none)
