Answer 1

1. create events.xml at following location.

app\code\Vendor\Extension\etc\events.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">
 <event name="controller_action_predispatch">
 <observer name="my_custom_observer" instance="Vendor\Extension\Observer\MyClass" shared="false" />
 </event>
</config>

2. Now create MyClass.php file on following location.

app\code\Vendor\Extension\Observer\MyClass.php

<?php 
namespace Vendor\Extension\Observer;
use Magento\Framework\Event\ObserverInterface;
class MyClass implements ObserverInterface
{
 public function execute(\Magento\Framework\Event\Observer $observer)
 {
 // THIS EVENT CALL ON EVERY URL
 // insert your custom code here, according to your requirement
 }
}
