title: Running a different CMS system under drupal folder
body: <p>I'm a drupal newbie...</p>
  
  <p>I completed my first drupal site. then client wanted to run their old CRM under new drupal site, they uploaded CRM folder into drupal folder, and when I try to address the CRM admin, as below, it redirects drupal 404 page (which is search page).</p>
  
  <blockquote>
    <p>www.blablabla.com/crm/admin</p>
  </blockquote>
  
  <p>Error message from drupal is below:</p>
  
  <blockquote>
    <p><em>The page you requested does not exist. For your convenience, a search
    was performed using the query 500
    shtml.</em></p>
  </blockquote>
  
  <p>is there any way that I can make drupal to ignore any folder under its folder? something via .htaccess, or I don't know :/</p>
  
  <p>Appreciate helps so much! thanks a lot!</p>
