      On this page Advanced Cache app module we give users the impression that site aware caching can be turned on by simply checking a box. This is really only part of the configuration required to make it work. Site aware caching is tied to the site definition. Each workspace needs a mapping which has to be created manually. For example, images in the dam will still go into the default cache unless the path they live under has been mapped to a site definition. The default cache is not site aware and will be dumped for all content updates.

      Checking the box changes the configuration of the flush policy. What if you have multiple cache configurations? Is this just changing defaultPageCache? This should be clarified. Perhaps even an improvement in the app where I can use a drop down to toggle between configurations.

      In the section "How to test" we need to add a link to a new troubleshooting page for cache (see DOCU-2044). Currently site aware caching is not working unless you use the workaround (see MGNLADVCACHE-111). Also, using the interface for verification isn't reliable (see MGNLCACHE-232). Instead users should be able to trace/debug the cache events in the log (see MGNLCACHE-231 & MGNLADVCACHE-110).

      Notes
      Publishing a home page triggers a complete flush:
