title: How can I redirect a subdomain to a specific URL?
body: <p>I am updating the Iirf.ini file to redirect <em>sub.columbia.edu</em> to <em>giving.columbia.edu</em>/<strong>video</strong>.</p>
  
  <p><em>sub.columbia.edu</em> is already redirecting to <em>giving.columbia.edu</em>.
  How can I go one step further to redirect it to <em>giving.columbia.edu</em>/<strong>video</strong>.</p>
  
  <p>Important Note: I would like the URL to show as <em>sub.columbia.edu</em> in the browser and not as <em>giving.columbia.edu</em>/<strong>video</strong></p>
  
  <pre><code>#Redirect subdomain to specific URL
  RewriteCond %{HTTP_HOST} ^sub\.columbia\.edu
  RewriteRule ^/$ /video
  </code></pre>
  
  <p>The above doesn't work. Any ideas how I should modify this?</p>
  
  <p>Thank you!</p>
