Newbie needs help integrating a custom web server with webstorm

So I need a custom web server because the built-in server doesn't support custom MIME types

This post

https://confluence.jetbrains.com/display/PhpStorm/Installing+and+Configuring+XAMPP+with+PhpStorm+IDE

details how to configure xampp with phpstorm. What differences are there between that and configuring an xampp web server to work with webstorm?

 Edit:

Forget everything I just asked about. It was more straight forward than I thought it would be. I just needed to ignore all the php stuff in the phpstorm tutorial. Now I need to figure out what to put in the xampp/htdocs folder so that my application actually runs.

Edit 2:

 After modifying the DocumentRoot in httpd.conf it works!  No additions needed to htdocs. Consider this issue resolved.
