For a quick fix, I defined the two directives in my squid.conf as follows: url_rewrite_extras "%>a %un %>rm myip=%la myport=%lp" store_id_extras "%>a %un %>rm myip=%la myport=%lp" Basically, I removed the ">A" part, which is responsible for the PTR lookup of client ips. Afterwards, squid does no more PTR lookups of client ips :) Thanks for the help ! _______________________________________________ squid-users mailing list squid-users@xxxxxxxxxxxxxxxxxxxxx http://lists.squid-cache.org/listinfo/squid-users
