I've got a Plone 5.2.9 site running just fine but there's a bit of a hangnail that's bothering me.
All my CSS, JS, and images come back as "304 Not Modified" which is great, except for these three:
These three and these three alone are always retrieved from the server with "200 OK". How do I convince Plone to treat these as "304 Not Modified" as well?
Registry settings, caching settings, and resource registry settings haven't yet yielded a clue—but then again, I'm a Plone noob!
