title: HTML form with different page redirection depending on input
body: <p>I want to have a box in HTML such as this one:</p>
  
  <p><img src="https://i.stack.imgur.com/49tjz.jpg" alt="enter image description here"></p>
  
  <p>Particular thing, I need to do this using only HTML (no PHP or particular langage requiring server, or particular installation).</p>
  
  <p>The reason for this is that it is meant to be used for HTML pages that will be opened from a USB key, not a website, and it has to be usable by any non-expert person. So no web-server configuration or installation required, such as what would be required for PHP, if I am right.</p>
