Is WebGL caching broken?

Hey,

When I first load the app, on incognito, it works fine. Second load, however, I get this:

PlatformGetStacktrace
UnityLoader.js:4 Exception encountered in operation Resource<TextAsset>(exptablebaseconfig.txt):

Nothing changes in the path, this is hard-coded in. Just running it twice breaks it. After getting rid of any cache etc, it works fine until it's restarted and then it's broken again. This happens for all assets that try to get grabbed.

 

In the group settings, there's an option for "use asset bundle cache". Try turning that off and let me know if that "fixes" the problem. I'm guessing something is going weird with caching in a browser.

 

Yep, this was the fix I did when making this post(ofcourse, no more cache as a result) and the build started working fine afterwards. A bit unfortunate! Caching is important for WebGL

 

Just wanted to check to see if there were any updates on this caching issue for WebGL builds? Disabling asset bundle cache fixed it for us too, but would be ideal to be able to keep caching enabled.

 

Resuming an old one, was this ever fixed?
UnityWebRequestAssetBundle.GetAssetBundle(url, version, 0); seems to ignore newer versions and always loads the old cache on WebGL.

 

Thanks, I am using 2022.1.7 and the WebGL cache is not great on Chrome. Is there a way to manually read the version number of the cached assetbundle and invalidate them? The class "Caching" doesn't work on WebGL.
