title: Multiple Django sites in Apache and DJANGO_SETTINGS_MODULE
body: <p>I'm currently trying to host 2 isolated Django web applications in one Apache instance. They work, however at random times a 500 HTTP error is raised.</p>
  
  <p>Apache's logfile reveals that sometimes application A tries to load settings from application B, which means that the environment variable DJANGO_SETTINGS_MODULE gets messed up between both applications.</p>
  
  <p>I tried to run both sites embedded and in daemon mode, no success. Any ideas?</p>
