RabbIt is a mutating, caching Web proxy used to speed up surfing over slow links like modems. It does this by removing advertising and background images and scaling down images to low quality JPEGs. RabbIT is written in Java and should be able to run on any platform. It does depend upon an image converter if image scaling is on. The recommended image converter is "convert" from the ImageMagick package.

mod_dav enables Apache to understand the WebDAV protocol (extensions to HTTP). WebDAV stands for "Web-based Distributed Authoring and Versioning", and is defined by RFC 2518. WebDAV is intended to replace proprietary authoring protocols such as those used by Frontpage or NetObjects' Fusion, but is also a complete set of protocols for manipulating a webserver's files and directories, and their properties.
mod_backhand is a load balancing module for Apache. It provides per-request HTTP redirection within a heterogeneous Apache server cluster. Each request is processed and run through a set of "candidacy functions" to determine which server is best suited to respond. The request is then proxied to that server. Facilities are in place to allow you to write your own dynamically loadable decision making algorithms. Everything about the request and the current availability of resources can be used in the decision-making process.
bib_errors can be used to intercept runtime errors of PHP scripts. It registers a PHP error handler function that outputs the details about the errors to a given log file. The errors can be displayed as part of the current script output or sent to a given email address to let the site administration or developer react promptly.
rest2web is a tool for automatically maintaining Web sites or parts of Web sites. It integrates with docutils so that contents can be kept in reStructured Text or HTML. It has a powerful templating and macro system and can automatically generate index pages and navigation trails (like sidebars and breadcrumbs). It generates static HTML and can generate relative links, which means that sites can be viewed from the filesystem. A "uservalues" system assists with creating sites in multiple languages.
