title: Can I set up variables for use in an apache configuration file?
body: <p>I have a php webapp convention that I'd like to follow and a lot of setup for it is done in the apache configuration file.</p>
  
  <p>Is there any way I can configure some strings that contain paths for multiple uses throughout the configuration file?</p>
  
  <p>A dim example might be:</p>
  
  <pre><code>EnginePath = /opt/engine
  AppPath = /opt/anapp
  
  DocumentRoot [AppPath]/Public
  CustomLog [AppPath]/Logs/Access.log combined
  
  php_admin_value auto_prepend_file [EnginePath]/EngineBootstrap.php
  </code></pre>
  
  <p>As you can see, I have lots of opportunities to consolodate several repeted occurences of the system and app paths.  This would make it easier to keep the configuration files as generic as possible, requiring a change in app or engine location to be edited once.  Rather than several times per configuration file.</p>
  
  <p>Thanks for any help!</p>
