I was working in MOSS recently and couldn’t see the Caching links. After I activated the Office SharePoint Server Publishing Infrastructure feature, the three Caching links didn’t show up. I can access them directly. Here are the links.
Output Caching
http://example.com/_Layouts/sitecachesettings.aspx
Object Caching

Caching Profiles
