Caching Gaussian Splats or other large files locally

What is the easiest way to get a web browser, or Babylon itself, to locally cache a gaussian splat (or other very large file) once downloaded and use the cached copy if present?

I have a few splats I am using in WebAR that are > 50mb, some even > 100mb in size. Chrome does not seem to cache them the same way it does images and such and so every time I load the webapp they redownload. My web host is going to kill me without a solution.

Just to make sure: you have closed DevTools or if opened, you unchecked “Disable chache”?
