Hi all, i made another squid.conf and then followed the steps mentioned at http://squidwiki.kinkie.it/squidwiki/MultipleInstances. The squid's first instance is used for the corporate network while the second one i uses for testing squid configurations and for optimizations. I was making acls for blocking images for second squid instance but it didn't worked i then tried couple of other acls but that were also not working. I then killed the second instace and applied the acls in the conf file of first squid and restarted and it was working. No the problem is that when when i m running both instaces one instance follows the specified acls while the second one is not follwong the acl. Both have differenct conf files. Thanks
