Summary

We have learned a lot about access control lists and access list rules in this chapter. We had a detailed look at the various types of ACL and how to construct ACL lists for different scenarios.

Now that we have learned about compiling, installing, configuring, and running Squid, we can try to deploy Squid on some test machines and...
