Hello Reader's! If you are stuck in a condition where you need to redirect old url. Then the quickest way to get previous url is by Javascript.
By using the document.referrer function.
Let's see the example below:-
<script>
var oldURL = document.referrer;
alert(oldURL);
</script>
As this script will execute it will make an alert box saying the old redirected url in it. And you can now it any where.
