Chrome: pause before redirect

debugger pause beforeunload

// Run this in the F12 javascript console in chrome
// if a redirect happens, the page will pause
// this helps because chrome's network tab's
// "preserve log" seems to technically preserve the log
// but you can't actually LOOK at it...
// also the "replay xhr" feature does not work after reload
// even if you "preserve log".

function createPause() {
  console.log('debugger breakpoint applied to beforeunload;');
  return function() { debugger; }
}

window.addEventListener("beforeunload", createPause(), false);

can't/shouldn't/rely on beforeunload etc. these days
