ifCached alternative for chrome partitioned cache about wiki HOT 8 CLOSED

Maybe it would be worth exploring when this technique would bypass the split cache? It probably mostly works when x.com requests a resource from x.com? Could you confirm? That could be presented as a nice split cache bypass.

I think so, ifCached_window probably could be more reliable it makes it harder to test.
Its now using the pagehide event to make the code smaller.
I will probably do more testing later.
Did you get the email I sent?

This seems to be more reliable

async function ifCached_window(url) {
  return new Promise(resolve => {
    checker.location = url;

    // Cache only
    setTimeout(() => {
      checker.stop();
    }, 20);

    // Get result
    setTimeout(() => {
      try {
        if (checker.location.href !== "about:blank") {
          // Origin has changed
          resolve(true);
          checker.location = "about:blank";
        }
      } catch {
        // No permission for origin
        resolve(true);
        checker.location = "about:blank";
      }
      resolve(false);
    }, 50);
  });
}

Split cache got disabled for me so thats why the testing was bad.

I would like to get it working without the window.open
window.stop() seems like a good replacement for the AbortController
Annoyingly dont know a way to reload a page bypassing cache using navigation (purge)

Maybe instant win.close()? Should be quite equivalent to window.stop()

from wiki.

checker.stop() works even if its a separate window.
The issue with checker.close() is that it requires window.open every time.
Cache test works however cache refreshing does not.
