Nope. Squid is designed to optimize traffic not to de-optimize it. So
does not do quota limitations.

However the OS QoS controls often do support quotas and do so far better
than Squid could even get close to. Squid can integrate with those using
tcp_outgoing_tos/mark and qos_flows to deliver per-request
classification tags to the OS QoS system.


If you stay wit a helper script you maybe could still optimize it a
little. Your log monitoring Script could be run as a log daemon helper
in order to get the log lines as soon as they are written. That also
lets you send a custom log format separate from the access.log to the
helper so it can work better.
