Commented logs below. I did 3 different types of connections. Let me 
know what you think. Because I'm logging the proxy host itself, it can 
be IP or name depending on the configuration. If you like it, want minor 
changes, additional logging, let me know and I'll adjust the code. As 
is, this is a one liner.
