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).

Mohawk is the next-generation, evolutionary leap from TkApache. It is a full-blown front-end GUI for the Apache Web server for configuration, tuning, performance monitoring, and more. Completely re- written in C, using GTK+/GNOME rather than Perl/Tk, Mohawk aims to be faster and more robust than TkApache.
