Privoxy – non-caching web proxy

Privoxy (Privacy Enhancing Proxy) is a non-caching Web proxy with advanced filtering capabilities for enhancing privacy, modifying web page data and HTTP headers, controlling access, and removing ads and other obnoxious Internet junk.

Privoxy has a flexible configuration and can be customized to suit individual needs and tastes. It supports both stand-alone systems and multi-user networks.

Privoxy uses the concept of actions in order to manipulate the data stream between the browser and remote sites.

Features include:

  • Ad blocking.
  • Cookie management.
  • Supports “Connection: keep-alive”. Outgoing connections can be kept alive independently from the client.
  • Supports IPv6.
  • Tagging which allows to change the behaviour based on client and server headers.
  • Run as an “intercepting” proxy.
  • Sophisticated actions and filters for manipulating both server and client headers.
  • Can be chained with other proxies.
  • Integrated browser-based configuration and control utility. Browser-based tracing of rule and filter effects. Remote toggling.
  • Web page filtering (text replacements, removes banners based on size, invisible “web-bugs” and HTML annoyances, etc).
  • Modularized configuration that allows for standard settings and user settings to reside in separate files, so that installing updated actions files won’t overwrite individual user settings.
  • Support for Perl Compatible Regular Expressions in the configuration files, and a more sophisticated and flexible configuration syntax.
  • GIF de-animation.
  • Bypass many click-tracking scripts (avoids script redirection).
  • User-customizable HTML templates for most proxy-generated pages (e.g. “blocked” page).
  • Auto-detection and re-reading of config file changes.
  • Most features are controllable on a per-site or per-location basis.
