title: How to find when a web page was last updated
body: <p>Is there  a way to find out how much time has passed since a web page was changed?</p>
  
  <p>For example, 
  I have a page hosted at: <code>www.mywebsitenotupdated.com</code></p>
  
  <p>Is there a way to find out when this HTML page was uploaded to the server?</p>
  
  <p><em>I have no access to server; just a link to the webpage.</em></p>
