I have two domains integrated in one CMS on my site.
I don't ever want the cached pages wp-content/cache/page_enhanced/testarchive.com/ to be deleted or marked .old once they've been created. They'll never change. More files will be added, but the files that already exist will not change.
Is there a way to do this? I'm on a dedicated linux (ubuntu) server if I need to change permissions or something.
