You can use ufdbGuard for this purpose. ufdbGuard is a free URL redirector for Squid which can be configured to read lists of usernames or list of IP addresses every X minutes (default for X is 15).<br>
So if you control a blacklist with usernames and write the name of the user to a defined file, ufdbguardd will block these users.<br>
If the user must be blocked immediately you need to reload ufdbguardd, otherwise you wait until the configured time interval to reread the userlist expires and so after a few minutes the user gets <br>
blocked.<br>
<br>
Note that reloading ufdbguardd does not interfere with Squid and all activity by browsers and squid continues normally.<br>
