If you modify any post or product Swift Performance will clear cache for archive pages as well. However in some cases – for example if you are using product carousel on homepage – there are some pages when should be cleared as well.
For this purpose you can use Clear Cache on Post Update feature. You can set pages which should be cleared when a new post was published or post has been updated. These pages will be cleared on any post update, for example if stock has been changed for a product. You can use Clear Cache on Post Update by Page or Clear Cache on Post Update by URL.
