I’ve been using Apache 2.2 for quite some time. Lately I’ve noticed CentOS and other distros using Apache 2.4. The new Apache breaks a bunch of stuff, as does newer php.
One thing that needed changing is a switch in directory listing tools. I have an archive on my web site that is running Scott Evan’s Indices software. It’s just a prettifier for file listings but it worked well and was easy to set up and configure for my personal taste. But this doesn’t work on Apache 2.4 for some reason. I haven’t figured out why. However I did find an alternative that works.
h5ai provides more functionality out of the box and is even easier to configure: copy a directory to your document root and add a new path entry to the default DirectoryIndex. I don’t have an example of this because so far I’m just using it behind a firewall at work. But it’s quite nice. Still need to look into customization options. But out of the box it’s quite useful.
