Just4Log is a library to dynamically enhance the performance of various Java logging systems inside a Java application. The source code in Java is not modified, but the optimization occurs on the compiled bytecode files. It optimizes bytecode from Log4j, Apache Commons, and JDK 1.4 java.util.logging. It can also automatically add "enter" and "exit" logs at every exit and entry point of methods. An Ant task offers integration in Ant scripts.
Mod_dtcl is a free/open source implementation of server-parsed Tcl under Apache. It allows you to tightly integrate HTML with Tcl, a widely-used scripting language with many years of development invested in it. There are also many external Tcl modules that you can load into mod_dtcl, to create images, access databases, etc.
JSPTemplates is a template engine that allows developers to write JSP pages that are very similar to the Sun API. The output of the pages does not have to be sent over the Web, and can be saved to a file or streamed in any other way. Any Java can be embedded in a JSP page, making the engine much more flexible than other template engines, and precludes the requirment to learn new syntax. It can also be used as a more flexible alternative to xslt for dynamically generating XML.
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_sequester is a module for the Apache Web server 1.3 which allows you to control access to Web documents according to the date and time of the request. It provides four basic ways to control access: allow until time t, allow after time t, allow between times t and t', and allow except between times t and t'. It is useful for controlling access to time-sensitive things like press releases (disallow until after), special offers (allow until), or windowed 'this week only' opportunities (allow between).
