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.

Primary features A Family of Internet Censorship Related Tools

This script will remotely fetch web pages for you, which is useful if you are in a restricted web environment (e.g. a censored one).

  • It does not help provide anonymity as it doesn't yet block Javascript.
  • gives you the option of retrieving a page unmodified
  • doesn't mangle mailto and nntp links
  • will fetch https resources if requested (with the accompanying security risk)
  • doesn't mangle local url references (within the page)
  • works in conjuction with approxClientproxy to allow fully transparent browsing through the proxy !
  • useful DEBUG mode (for http and CGI environment disgnostics.. including cookies)
  • doesn't generate XHTML that IE can't display
  • It's written in Python and so a lot easier to adapt !
  • Will handle cookies automatically using the ClientCookie or cookielib module, if they're available.
  • Can be set to only allow access to a specified domain by setting the RESTRICTED variable.
