I like that it has an easy to use interface for creating pages with HTML5 templates as well as PHP content management scripts - which are stored in separate folders (templates & php). The fact that you can create your own custom modules using C language makes development of new features easier than if done from within html files or cgi script examples provided by default. Also its very light weight so there's no extra load when running multiple virtual servers simultaneously. Not much dislike about this product at all actually! It serves my needs pretty perfectly without any problems whatsoever. We've used appwebserver over other products we tested because they have been proven reliable enough for our purposes since many years now while others didn't even come close to their level of quality assurance/support.
