miniLogger is a very small (4 classes and a 10KB jar) and easy to use logger. It uses a logging API that is a subset of JDK 1.4 logging but works on all Java 2 versions. It has been tested on Windows, Solaris, IRIX, and Linux for versions 1.2 and 1.3 of the Sun JDK. It supports logger control from the command line. Logger names are hierarchical separated by dots, and selecting any name automatically selects all names below. If logger_name is an empty string, it will affect all loggers. The loggers and level options are evaluated from left to right. It prints the thread name, source file name, and number line by default, and output can be redirected from System.err to file or any PrintStream. Finally, the logger hierarchy can easily mirror a package/class hierarchy or can be arbitrarily defined by the user.
mod_atrack adds advanced user tracking functionality to the Apache Web server. It was based on mod_usertrack and introduces many new configuration features primarily designed to reduce the annoyance of sending multiple cookies to a single user and allow more intelligent analysis of collected data.
mod_authenticache provides a simple and generic method for caching authentication information on the client side in order to enhance performance. It has been tested with several Basic HTTP authentication modules, and has an Apache 2.0.x optional function exporter for caching credentials from any custom authentication module.
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.
