Download cap using squid in linux.

[Vivek Sharma <vivek@xxxxxxxxxxx>]

 Is there a way we can do following things using squid.

1. Put an upper cap on total Download size in a month per user (users 
are configured on LDAP).
2. Put an upper cap on the no of hours of usage per month per user.

I shall be obliged if someone can tell me an alternate solution not 
there by default in squid.

Thanks in anticipation.

regards,
Vivek
