It's apache2, nothing particuarly exicting.

==== Creating web config ====

You should have a section of config for yourself that you can edit, in /etc/apache2/sites-available/$USER

==== Reloading site configuration ====

Again assuming you're in the webmasters group, you will be able to run the init.d script to reload apache configuration

  sudo /etc/init.d/apache2 reload
