Custom Squid acl

[ghido]

Hi all, i set my custom acl in custom options on the pfsense squid gui.
for avery auth user i permit only e list of site, but in pfsense doesn'y function:

acl user1 proxy_auth user1;
acl user2 proxy_auth user2;
acl user3 proxy_auth "/var/squid/acl/vietati";
acl siti_user1 dstdom_regex -i "/var/squid/acl/siti_user1.acl";
acl siti_user2 dstdom_regex -i "/var/squid/acl/siti_user2.acl";
acl siti_user3 dstdom_regex -i "/var/squid/acl/siti_user3.acl";
http_access allow user1 siti_user1;
http_access deny user1 !siti_user1;
http_access allow user1 siti_user2;
http_access deny user2 !siti_user2;
http_access deny user3;

the auth is OK

Thanks a lot
