I have charged my local network with over 50 users, however they usually use the programs as FlashGet, DAP, IDM to get file from Internet. They open more connection ( 10 connections/time download).
So, how can i limit those programs or how can i limit connection get data of user with Squid proxy.

Thanks so much.

Use Iptables ( -m limit option).

Also try limiting bandwidth using "delay" in squid.

Thanks for your reply,

Can you give me some example about --iptabless with -m limit option -- ? I am not clear about.

The first time, i also use bandwith limit with Squid proxy, however having something not to be suitable for my localnetwork's working purpose.
Here is my delay configuration:

# nolimit download in localnet
acl nolimit-localnet url_regex -i 192.168.

# nolimit download from specific users in localnet
acl nolimit-users url_regex -i 192.168.1.80 192.168.1.81 192.168.1.90 192.168.1.20
