1131151 - importScripts() caches, never refreshes

Status: RESOLVED DUPLICATE of bug 976045

(Core :: DOM: Workers, defect)

Description

[Davide]

User Agent: Mozilla/5.0 (X11; Linux i686; rv:31.0) Gecko/20100101 Firefox/31.0 Iceweasel/31.3.0
Build ID: 20141203101556

Steps to reproduce:

importScripts('script.js') keeps importing an outdated cached file, even when reloading the page with ctrl+f5.

Typing the script address directly into the address bar correctly shows the updated script.js, and appears to refresh the cache used by importScripts thereafter.

This is consistently reproducible.

Hi baku, I was about to open a new bug about the problem that I commented about the importScripts stuff, and this bug is exactly that one.

In order to bypass this, I had to use the old trick:
importScripts('script.js?nocache=' + new Date());

Otherwise, the script is always cached.

The problem is that the semantics of "ctrl+f5" are not well defined and all the proposed definitions are broken in various nasty ways...
