Thanks. I defined the following, and it worked as expected: url_rewrite_access deny allowed_domains url_rewrite_access deny allowed_ips url_rewrite_program /usr/bin/squidGuard url_rewrite_children 80 startup=10 idle=3 How can I rewrite a URL in squid without a helper such as SG? ie. how can emulate SG's "rew" in squid.conf? Thanks, Vieri
