Web player caching is not happening in only Safari browser.

Hello,

I am using the following code to load each scene in game and this LoadUnityWeb is very easy load scene contents one by one than Assetbundles (Thanks Unity).

But the caching in web browser is giving strange error. Only in Safari I am facing caching is not happening. But, In all the other browser caching is happening and second time scene loads very quickly.

 WWW stream = new WWW (streamURL);
         
  while (!stream.isDone)
  {
      downloadProgress = stream.progress;
      yield return null;
  }
         
  stream.LoadUnityWeb();

Can anyone please assist in this, like do I need to set anything else in Unity.?
