Clear native browser cache with JavaScript

[LJWatson]

Migrated from Bugzilla 26666.

From the original issue:

"There is no way to force the browser to clear the cache of all the artifacts of your domain via javascript.

I'm humbly suggesting a simple window.navigator (most likely) exposed method for flushing the native browser cache of all artifacts of your domain.

Very useful for making sure the visiting client has a cleared cache for their next visit to your site / application.

navigator.browserCacheClear(); //something like this.

There would be no WRITE access to the cache, no inspecting READ access, but simply the ability to throw an API call in the hopes of your browser cache being cleared for your domain.">

I think this is covered in Service Workers cache interface so closing here. I suggest that is a more appropriate spec for filing an issue if there is something that isn't sufficient.
