Can you provide any update on the Joomla cache extension? I am thinking about having a freelancer put something together if this is still years down the road. I just need a way to clear the cache for single pages that are changed without having to flush the entire site cache each time a change is made. Using a ?nocache work kind of works but even then sometimes the page changes are not reflected in the uncached version. I am thinking that the cache rules in the plugin will have to be much more complex in order to map single cache files to pages. I have something similar already set up in NGINX and with that I can just go in and manually clear the cache for that certain page by the friendly URL.
