I, like many people, have a relatively out-of-the-box Apache installation with a lot of default "LoadModule" lines.
Since the beginning, I've installed a lot of software, and to be honest, I don't know what software is is using which modules.
I would like to reduce the memory footprint of my Apache instances, and to do that, I'd like to remove modules from being used. The only way that I know of to determine if a module is in use is to remove it from the configuration and see if anything breaks. This is bad in more ways than I have time to describe.
I would like to know if anyone is aware of a way to get Apache to report which modules have been "used", or if there's another way to programmatically determine whether a module is safe to unconfigure.
