Steps to reproduce:

2) Build attached project
3) Install XAMPP
Download XAMPP from here: https://www.apachefriends.org/index.html
4) Create folder and rename it to 'Cache' in C:\xampp\htdocs
5) Add built project in recently created 'Cache'' folder
6) Launch XAMPP's Control Panel
7) Start Apache module
8) Open Firefox browser and enter: http://localhost/Cache/index.html
9) In the browser, click on Developer settings >> Web Console(Firefox)

    Thanks,

    That really works in Chrome and Mozilla Firefox after upgrading to Unity 2018.3.1f1.However for us it looks like it fails in case of Safari Browser.Just looking for a workaround.

    I am using Safari version (11.1.2).Unfortunately, it's unable to cache the "WebGL.data.unityweb" of size 48MB and the Asset Bundles.The large data file is downloading every time.

    Does the above fix applicable for Safari also ?

    I am getting the following errors in console (Safari Browser):

    1.[UnityCache] indexedDB database could not be opened

    2.[UnityCache] WebGL.wasm.framework.unityweb' successfully downloaded but not stored in the indexedDB cache due to the error: Error: indexedDB access denied

    3.IndexedDB is not available. Data will not persist in cache and PlayerPrefs will not be saved.

    How would I be able to find a way out?

    Thanks
