title: show notification in jsp page depending on a flag?
body: <p>I have HTML code in the jsp page that I want it to be displayed only after the user submits data and get redirected to this page. So I have to set a success flag as a parameter in the link like:</p>
  
  <pre><code>http://site.com/page?success=true
  </code></pre>
  
  <p>Not sending in the request because it will be lost since I am redirecting
  I don't want to send it in the link as a parameter and I am thinking of another way
  and ideas how to send it? So the link will be:</p>
  
  <pre><code>http://site.com/page
  </code></pre>
  
  <p>and I can display the the html code?</p>
