Something else most may have not known about apache is it has a built-in server-side scripting feature, think php w/o loops, called mod_include http://en.wikipedia.org/wiki/Shtml In the purest sense though, it is templating for html.

This feature is a bit dated and unnecessarily redundant if you write php, but could be great a addition if your back-end requires CGI or you don't wanna 'messy' up your pretty mark-up with php. ;)
