Re: IPCHAINS Implementation

Dear Amber,

Thanks for the info.

One more query.  In squid.conf file which parameter is used to block
unwanted sites.  Do we need to create seperate ACL's (Access Control List)
for each site ??  Please put some light on this and if possible give some
examples too.

With regards
