title: Apache: How to set different root folder depending whether user local or from outside network
body: <p>I have a root directory <code>/Users/username/Sites/</code> that I use to test sites locally. I want to expose only one of the subfolders <code>Users/username/Sites/subsite</code> to requests that come from outside the network.</p>
  <p>I already have port forwarding setup and I'm able to see the root directory when I log from my dynamic DNS service.</p>
  <p>What do I have to do to Apache to have this work? I've tried several searches but I can't seem to come up with the right wording to get an answer to my question.</p>
