We're using [[Media:Example.jpg]] to include versioned pdf files. New versions of the file are uploaded via "Upload new file version" on the file description page.
After having uploaded a new file version, the browser keeps returning the old version until the browser cache is being flushed with "Ctrl+F5".
Question: Is there a way to ensure the newest file version is being displayed without having to hard refresh the page manually? Shouldn't mediawiki pass some kind of "expired flag" when a new file version is available?
