Hi, How can squid slow down clients (Browsers) making a lot of hits (over 100 000 hits per day) by staying connected all day and night to web sites doing page refresh up to 30 per minute (increasing also the size of access_log) ? Same question if download is over 20 Gb per day. delay_pools seems to solve this problem with static IP ACL. I wish to reduce bandwith automaticaly and only for IP abusing networks ressources and give again full bandwith when request decreases.
