title: from http to https
body: <p>I have a simple web app: a web page with a form to submit, and a servlet on the server side. </p>
  
  <p>It works. </p>
  
  <p>I am now asked to change it so that the address of the form changes from<br>
  <a href="http://www.example.com/myForm.html" rel="nofollow noreferrer">http://www.example.com/myForm.html</a> to <a href="https://www.example.com/myForm.html" rel="nofollow noreferrer">https://www.example.com/myForm.html</a></p>
  
  <p>What are the steps to do this? Do I have to change my servlet? My deployment? My web page? 
  All of them? </p>
  
  <p>Thanks.</p>
