Wondering what is the X-Drupal-Cache is?
Hope your familiar with Drupal, Drupal is a popular content management system huh?. Yes! it's not just a content management system it's a content management framework that allows you to create any web application on top of it's powerful core.
Okay, now back to the topic :). What is
X-Drupal-Cache?. I saw that first time when I install my Drupal7 + Varnish website, I just wanted to see if my pages are from the Varnish and not a MISS so checked headers. Then I went to the code base of Drupal and search for
X-Drupal-Cache. It is really simple you see
X-Drupal-Cache if the pages are from drupal page cache. If you enable page cache and when anonymous users access your website they see this header.
Check out Set X-Drupal-Cache header during
page_cache_fastpath and Implement better cache headers for reverse proxies for more information about the
X-Drupal-Cache header. It seems to be a Drupal 7 only thing.
Going forward you might not like to show that to your users, right? You can use
drupal_add_http_header for that.
