How do I restrict access to only one website through my Squid proxy?
The following doesn't work...
acl amazon_ireland src 22.214.171.124/17
acl some_site url_regex google
http_access allow amazon_ireland
http_access allow some_site
http_access deny all
Have a look at the squid FAQ, there is a perfect example for your setup.
acl GOOD dst 10.0.0.1 http_access allow GOOD http_access deny all
if you want to match by domain-name
acl GOOD dstdomain .amazon.ie http_access allow GOOD http_access deny all
