Round robin parents get the same URL

Hello,

I try to setup 2 round robin parents to my Squid (1.1.20).
Problem: some URL (around 3 %) are sent to the 2 parents.

Any idea?

Thanks in advance.

Emmanuel.

PS 1:

Here is an extract from the squid.conf file:

cache_host pcnt parent 3128 7 no-query round-robin weight=4
cache_host pcnt2 parent 3128 7 no-query round-robin weight=1
