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_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).
Mod_trace_output is an Apache module that is designed to store the data that was sent to a browser, even if the request was for a dynamic page. It is possible to use it to generate statistics on the content viewed by users, and can store captured pages in files or in a MySQL database.
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.
