How to detect URL and redirect to 404 if it contains script tag

I have a webpage for example www.testing.example.com/home, now if someone manually add script tag onto the url bar like www.testing.example.com/home/<Script>alert('asd')</script> then it should not give alert, it should redirect to 404 page.

I want to say if my url has script tag then it should redirect to 404 page apart form giving the alert message.

How can this be achieved using Javascript?

var regex = new RegExp("%3c.*%3e","i");
var script = regex.exec(window.location.href);
if (script) {
    window.location.href = "/404";
}
