title: Do I need to ping HTTPS or just HTTP?
body: <p>I am attempting to connect to URLs in Java to see if they are valid and I am wondering if I need to connect to HTTPS(port 443?) or if connecting to just HTTP(port 80) will be enough. </p>
  
  <p>Does connecting to HTTP for an HTTPS website work? Is there anything with firewalls I should watch out for that wouldn't allow me to do this?</p>
  
  <p>Thanks.</p>
