A Tinyproxy Transparent Installation on Ubuntu 12.04 with HTTPS Support

Update: It appears as of June 2013 that the Ubuntu repositories now have compiled Tinyproxy with transparent support.  So unless you want to build from source for any other reason you may be better off following my tutorial on installing Tinyproxy on Ubuntu (just remember to change the default port numbers as appropriate).

The repositories for Ubuntu don’t have Transparent Support enabled for Tinyproxy.  Some firewalls and corporate installations need to use transparent proxies if they are internally redirecting.  This post will guide you through building Tinyproxy from source on Ubuntu 12.04 as a complete installation and working system.

I couldn’t find any decent guides out there on how to make this work, so I thought I’d put one together.  Hopefully my research will come in useful for someone else…  Warning this is a little more in-depth than my usual tutorials, but I promise it will be worth it in the end.
