roxen and apache were not two subtly different tools, they were, and still are, miles apart. the way you use them and develop for them is completely different. roxen not only replaces apache but also perl, php or any other language that you develop your websites with. therefore roxen does not even compete with apache, but it also competes with laravel, django or rails. the fact that those later frameworks need apache to serve their content is rather incidental.

rails was first released in 2004. django in 2005, laravel in 2011. i used roxen (and it's predecessor spinner) in 1994!! that's literally a decade earlier. i think the only possibly competing tool available at the time was cl-http in lisp[0]. (AIDA/Web for smalltalk was created in 1996, as was WebObjects, Java EE came in 1999. that's all i could find so far)

[0]: at the time i was looking for a better alternative to the available ncsa and cern webservers. i remember ordering a student version or something like that of franz lisp so i could try it. and i was put off by having to write lisp code just to serve static files. that was what made me keep looking until i found spinner.
