i have been using squid + squish (http://www.ledge.co.za/software/
to control the user access for quite some time.

Lately, i found out that MSN connection is still attach when the
squish limit for that user is exceeded.

The MSN connection will only "detach" if and only i restart the squid.
But the problem is restarting the squid will cause other FTP
connection to time out.

Is there anyway that i can stop the squid+squish MSN connection for a
user when the limit is exceeded ?
