--- Comment #3 from Jeremy Newman jnewman@codeweavers.com --- We recently changed the expire time on the CDN files to 1 month to save on bandwidth on the origin server. We can set expire on individual files, so I'll set the expire on the Packages files to 1 hour since they are small.
I'll also issue a manual cache flush on the same files.
