How would I approach clearing the cache in the scenario where I have a wildcard page in my site
e.g. /sitecore/content/MySite/Home/Products/*
which references another section of the content tree such as
/sitecore/content/MySite/Data/ProductCatalog/
Say I change a product under /Data/ProductCatalog and publish, how can I ensure that the cache is cleared for the correct page/URL?
