When I update files for a game via Dropbox, it caches it. Isn't there a way in HTML5 to turn off caching in the header? Is there a way to work around this other than turning off caching in my browser? I want to make sure people that I send my links to have the most up-to-date version of the game. I send the same people the updated versions. It is just a very tedious task for them to force reload pages and for me to tell people who are not aware of caching that they need to press Ctrl + R.
