Is there a way to have wp-super-cache delete the cached item if (and only if) the page has changed?
What I'm getting at is that my site is mostly static. I am using WordPress as a CMS and not a blog engine. So, comments are disabled and the site only gets updated when I update the content of the site - which is somewhat infrequently.
Would what I am talking about be better served by setting the cache timeout something like a year and turning on preload? Do I need to check the "Clear all cache files when a post or page is published" option if this is the route I should go?
As an aside, have the authors looked at the (very mature) Boost project over at Drupal? It has quite a bit of the same functionality and is GPLed, so borrowing ideas from them would be inline with their licensing.
