C.O.D. posted a guide about turning your Windows Home Server into a Free Proxy Server

There are more uses for your WHS then you can shake a stick at; whatever that may mean. The latest endeavor is using your Windows Home Server as an Internet Proxy. I personally use my Windows Home Server as a proxy to be able to view sites that my company blocks access to. Setting up a proxy can also allow you to control web content served in your home. If you have a child, you can block sites or even keywords to keep pages from being served.
