By adding a random string to the path of the js file every time, we make sure to never hit the browser cache.
By setting the response header "Cache-Control" to "no-store" and setting "Expires" to 0, we make sure the browsers and place calling this never store it in cache.

I would only approve the second even though we may never have exact control over browser caching on a particular Android/iOS/PC device. |

@Moustachauve can you revert HTML changes and only do backend change? |
|
Unless @softhack007 has a strong opinion, I will revert the HTML changes tonight. |
Fine for me 👍 |

Some browser, especially Android webview, have more aggressive caching strategies and might sometimes cache the response of the settings JS.
This implements two strategy, one in the back-end and one in the front-end. Two might be overkill, so we could keep a single one if needed.
Front-end strategy to prevent caching
By adding a random string to the path of the js file every time, we make sure to never hit the browser cache.
Back-end strategy to prevent caching
By setting the response header "Cache-Control" to "no-store" and setting "Expires" to 0, we make sure the browsers and place calling this never store it in cache.
