Foxy is a content filtering HTTP proxy. It can rewrite web pages on the fly using its internal filters and external user-written scripts.

* Hides IP address and browser/OS information by spoofing sensitive HTTP request headers (X-Forwarded-For, User-Agent, Referer, or any other header).
* Allows to surf anonymously using public proxies. Any number of proxies can be used; different proxies may be used for different sites.
* Disables Google, Yahoo, and MSN click tracking mechanisms, speeds up your search, deletes commercial noise (like "sponsored links") from your search results.
* Kills popups, banners, cookies, "web beacons", blocks server-side spyware.
* Blocks access to porn or other inappropriate content using dictionaries (parental control). Content is analysed on the fly, so all known and yet unknown sources are blocked.
* Tracks users' online activity and generates traffic reports.
