unity webgl data caching not turning off

hi, for apple product we need to remove the data caching.

It worked previously and we could see the game reloading each time we test it on the server.

Now the data caching is unchecked but it still cache the game. On Firefox and Chrome after 1 load, the second time it load instantly. This mean the data caching is on.

This is a huge issues and we are in a rush right now, If we can't remove the data caching, we can't play the game on many apple devices.

We make sure to replace every file, the index.html, all release and templateData folder to make sure there is nothing from the last build.

Even uploading it on a new directory will not work meaning that it is not a server issues.

note: the game do not use any streaming asset, Resources folder or Playerpref function
