Reading this interesting article about HTTP proxies, discovered Middleman, a small HTTP proxy. Apart from doing an excellent job of filtering out ads it does all sorts of fun stuff like show you HTTP headers, log HTTP traffic, and allow wonderful URL tricks. Also very configurable. It even fixes a weird probelm I've been seeing with Mozilla and IIS web sites, AND (and this is really cool) it properly makes links out of URLs that aren't. Everyone should have one.
