Need help for Configuring Squid-2.6

Hi,

Previously I was using squid-2.5 accelerated but due to link breaking issue, I have upgraded it to 2.6 but i am unable to configure it with accelerated support. Kindly help me to make it accelerated proxy server.

My 2.6 squid.conf :

Squid version - 2.6
squidGuard - 1.3
OS - Freebsd - 6
pf firewall

I have tried with accel, vhost , cache_peer options but I am unable to properly configure file, so I have started squid without accelerated support. Kindly help me to configure squid with config file examples.

Thank you
