I use the AWPCP plugin and need to ensure that super-cache recognises when a new advert is placed. Currently all adverts that were made after I enabled super-cache are not displaying on the advert 'home' page because I'm being served a cached version of it. Then I have another problem - this plugin comes with a widget which shows the latest 5 adverts, and of course these are not changing either when new adverts are added. Unfortunately the widget displays in the sidebar on almost every page so I can't really just turn off caching for those pages or there isn't much point in caching at all - I need a way of super-cache recognising when a new advert is placed and recaching the adverts home page and instances of the widget. How would I go about doing that?
