I'd love to see a .js cache buster so we don't have to tell users to clear there cache when the app is upgraded.
The relatively simple but manual method I used now is to append a query string to the <link rel />
i.e.
<link rel="stylesheet" href="/ext-js-all.js?v1.0"/>
<link rel="stylesheet" href="/ext-js-all.js?v1.1"/>
Not too hard for me to manage, but one more item on the grow list of 'thinks to do when upgrading Aware'. The shorter that list the better - since we humans (and especially me) are prone to error! 🙂
