How to redirect to external URL in Laravel with/without Inertia

Regular Laravel:

return redirect()->away("https://foo.com");

question
What’s the difference with regular redirect() method? From the Laravel docs: redirect()->away() “creates a RedirectResponse without any additional URL encoding, validation, or verification”. Both methods work, but it’s more efficient to use away (ie. no need for additional URL encoding etc) if we know it is an external URL.

Laravel + Inertia:

use Illuminate\Http\Request; // or class that extends it
use Inertia\Inertia;
 
public function foo(Request $request) {
  $redirectUrl = "https://foo.com";
  // ... 
  if ($request->inertia()) {
    return Inertia::location($redirectUrl);
  }
  return redirect()->away($redirectUrl);
}
