What is a HTTP proxy?

A HTTP proxy acts as an intermediary between a HTTP client (i.e. browser) and HTTP server. It receives all requests from the browser, and relays them (possibly modified) to the server. Likewise, it receives all responses from the server, and relays them (possibly modified) to the client. HTTP Proxies can be used for a wide variety of tasks, including filtering, logging, caching, etc, etc, etc.

Features

htfilter is a lightweight HTTP proxy server that can monitor, filter, and cache HTTP requests and responses. It has no GUI, but it's extensible using custom Python code. You can hook into the intercepted HTTP conversations and modify them as appropriate. This makes htfilter a useful debugging tool.

This script is designed to be a protocol testing tool. If you're looking to mess with other people, this is not for you.

Included are some sample hooks:

  • RewriteYouTube - detects YouTube videos, redirects to their MP4 versions, and archives them with meaningful filenames
  • RewritePandora - detects Pandora music, archives them with meaningful filenames, and writes tags
  • RewriteExample - blocks Microsoft websites, JPEG images, and cookies
