log file question

Hi all,

              In my office i have installed squid ( In RedHat linux 5.2)
and it is working fine. Since more than 100 users use squid, my log
files grows enormously. Whether it is possible to set any parameter in
/etc/squid.conf file so that as any of the log file size go beyond 20MB
, the squid system automatically renames the log files. Say, if
access.log file exceeds 20MB, it renames it as access.log.1 and a new
access.log file is created with size =0 bytes.

I think i have made myself clear. Basically, i do not want to delete
the log files , but only to rename after it reaches a specific size
limit.

Can anyone help me out in this.

With regards
