javascript - Why won't the client receive new versions of this script in the public folder?

Question

In my project there is a public folder and a script inside it: public/worker.js, which contains a piece of code:

alert('foo');

I call this script using a Worker:

new Worker('worker.js');

I launch Meteor and connect to my app. foo is alerted.
If I change the public/worker.js code to anything else:

alert('bar');

The server refreshes the clients, the client refreshes the page but won't get the new code, instead using the old one (alerting foo instead of the new shiny bar). Clearing the cache then refreshing fixes the issue. CTRL+F5 does not fix this cache issue, it does not seem to work for this kind of script call (at least not on the version of Firefox I tested it with).

Why is this happening, exactly?
How can I prevent it?

You should alter the response header for the file. Maybe this gets you going: Explicit HTTP Response Headers for files in Meteor's public directory
