title: Getting Exception with code for finding broken links in webpage with Selenium Webdriver
body: <p>I wrote this code to get the HTTP response of any links and based on that I am printing if the link is valid or not. But every time when I execute the code, it is going to the catch block. Can you tell, where am I making the mistake?</p>
