Apache modules
I am responsible for a couple of Apache modules (v2.2 unless specified otherwise).
mod_sqltemplate
This module provides a way to template your Apache configuration files based on values stored in an SQL database. For more information, see the mod_sqltemplate page.
This module is currently under active development.
mod_optinclude (coming soon)
This module allows you to include files without an error if the file does not exist, as well as providing configuration blocks that are only executed if a given file or directory does/does not exist.
mod_fakephp
This is a very simple module that installs null handlers for the various PHP configuration directives, to allow you to use the htscanner extension. For more information, see the mod_fakephp page.
This module is currently in use on this webserver.
