Autodelete

I am using apcu manager on a news site. Every time new content is added, updated, deleted, the homepage must be updated as well. However, this process can only be performed manually only by users with admin privileges. That’s why we can’t use the app.

How can we keep the homepage up to date?
How can we auto clean(delete all) apcu when content is added, deleted, updated by editors. (Would doing this cause a technical problem?)
