Varnish multiple domains but images shared

Posted Thu, 10/08/2015 - 16:59 by admin

Ever had a Drupal multisite where the images are all stored in the same folder and shared for all sites? Ever installed varnish and noticed how much RAM gets used by photos? Well I did, and realised that I had 5 copies of every image, one for every domain. Easy thing to fix this:

  if (req.http.host !~ "^maindomain\.com" && req.url ~ "my/images/folder") {
    set req.http.host = "maindomain.com";
  }
