 * Hi. I saw the minified or Combined CSS and JS has query strings attached to it.
   Does quic CDN cache these files? Or rather, is quic.cloud query strings friendly?
   Some CDNs are known not to cache query strings (properly).

 * Hi,
 * the query string was specifically added to avoid browser cache , so when you 
   change something in your site , browser won’t use old cache.
 * yes , QC does cache them

 * well , I am not familiar with that.
 * but I don’t see a reason for CDN why not query string friend , most CF I’ve used/
   tried , does have an option to either vary on query string or discard the query
   string.
 * Best regards,
