title: Is it possible to have VCL file definitions made dynamic
body: <p>Behavior of Apache Server can be controlled from a variety of configuration file but they boil down to two locations -
  1) a .conf file in the apache installation folder 
  2) .htaccess file</p>
  
  <p>Can Varnish be configured in a similar way so that it can take up vcl definitions in real time..</p>
