[ale] /etc/hosts and caching

[Richard Bronosky]

Geeh, I'm glad someone read my demo! You can talk all day long, or you can
code a proof. I encourage my developers to do that because at least 20% of
what they find on the internet doesn't apply because of config differences.

I also would encourage the OP to try putting IP addresses into the
applications to see what that does for performance. Unfortunately the
concept of "test instead of talk" does not go very far on this list.
