JunkEx - A filtering HTTP proxy based on the JunkBuster

JunkEx also incorporates ideas and code from Carsten Clasohm's LeanWeb and Stefan Waldherr's version of the JunkBuster.

Note: JunkEx can be considered dead currently.
Privoxy is the continuation of Stefan's line and is currently far ahead of JunkEx.

What JunkEx can do for you

(JB) means also present in the "usual" JunkBuster

Protect your privacy by filtering specified HTTP header fields including cookies (JB)
Filter annoying banners (optionally replace them with a tiny image) (JB)
Remove unnecessary clutter from often visited sites
Kill pop-up windows without entirely disabling java-script

What it cannot do

JunkEx is not a caching proxy. However, it may be combined with other proxies (e.g., Squid).
At the moment JunkEx is not able to filter pages by their content. This feature will be possibly implemented in some future version.

Obtaining

download v1.2.5, tar xzf ..., make, run & have fun.

Segfaults when logfile cannot be opened.

download experimental v1.90pre2

Changelog

1.90pre1
- Much more complex body filtering rules
- Preliminary page blocking by content (not really usable)
- Support for compressed content-concoding; transfer-encoding is ignored, so it may cause major trouble with some http/1.1 servers. Just untested.
- Basic referrer forging support
- Cookie "expires=" field removal support -> you can still use pages which require cookies without major loss of privacy
- Some statistics support (not really usable)
- Removed M$-Windows support

1.90pre2
- Fixes

Possibly some day to come (version 2.0)

Site-dependent HTTP-referrers. This way you can open sites directly, which normally can be reached only by clicking a link on a certain site.

Page blocking based on keywords.

Other things ToDo

Update/merge the documentation to match the current features. Any volunteers?

Update documentation coded directly into the program, such as links to the original JunkBuster site, version information, etc..

Use automake/autoconf to simplify compilation. Separate Makefiles for systems without a sh-compatible shell.

Bugs

Probably tons of them. This code is hardly tested, although the new body filtering seems quite stable.
Don't hesitate to report bugs. I want to know about them! Please always tell me the exact URL (if the problem is related to a specific site) and your configuration settings.

Installation

The simplest way to install JunkEx is to install the version of JunkBuster packaged for your OS distribution and replace the existing executable or adjust the daemon position to the place where you put JunkEx. Then adjust the already present config files according to the ones shipped with JunkEx.
