Con Multiple steps
Some things require multiple steps, like creating a listener and a virtual host or a reverse proxy.
Con Arcane configuration format
Configuration is as good as the manuals go. As soon as you have to configure it by yourself, it becomes a lot more difficult due to a rather obtuse system of configuration with long and confusing variable names, which has become infamous among web developers.
Con Process Based Request Handling
Each request opens a new process/fork to handle just that request (ver memory inefficient)
Con Extremely inneficient
Opens a new thread for each request. In practice this means that unless you use a proxy (nginx) you can only have a certain number of people on your site at a time, and is extremely inefficient on the server side.
