In previous documentation, we've configured sites to use NGinx as a Reverse Caching Proxy, leading to hugely improved response times on popular content. We've also implemented a custom configuration so that we can refresh the cache periodically, ensuring that dynamic content (such as Twitter modules) updates.
One thing we haven't done as yet, though, is to address the issue of internal hitcounts. We've looked specifically at using NGinx with Joomla, and noted that a side effect would be inaccurate hitcounts displayed within Joomla (which remains true even when using the internal page caching).
In this documentation, we'll be implementing a small script to ensure that hits served from the cache are still recorded within Joomla (or Wordpress, Drupal - whatever you happen to be using), albeit a little while after they happen.
