h5ai is a modern HTTP web server index for Apache httpd, lighttpd, nginx and Cherokee.<p>It was originally designed to work with Apache's mod_autoindex. This use case is still supported, although the main focus now is on the PHP version. The PHP version allows features that need server side processing of your files (e.g. thumbnail generation) and is working with other HTTP web servers too. Tested HTTP web servers are: Apache httpd, lighttpd, nginx and Cherokee. The front end supports all modern browsers: Chrome, Firefox, Safari, Opera and also IE7+ (with some features disabled in IE7+8).
