How to force the browser not to cache JavaScript?

Question

JavaScript

Is there any efficient way to force the browser not to cache a particular Javascript file? It is desirable that this method works in Firefox, Opera and Chrome (IE is not particularly interested).

Answer 1

change the file name.
for example, you can script.js?123
instead of a number, for example, I substitute the hash sum of the file

Answer 2

Or maybe it's easier, on the server side, to include the script directly in html? The script will be reloaded every time the page is refreshed. Usually this is extra traffic, but in your case it will not be superfluous. you need to update the script constantly.

Answer 3

Set the correct headers using the web server.

Answer 4

In all browsers I refresh the page with Ctrl+R. Never had a problem with the cache.

Answer 5

In ff, I disabled caching by setting netwotk.http.use-cache to false.
Tough but it worked.
