title: How to prevent "A potentially dangerous Request.Form" in a request
body: <p>I have added a <a href="http://www.freetextbox.com/" rel="nofollow">FreeTextBox</a> control in my page, which allows users to insert HTML tag. Well, when I send to the server, I get the following error:</p>
  
  <blockquote>
    <p>A potentially dangerous Request.Form value was detected from the client (GestisciPagine1_txtTestoPagina="...t homepage<code>&lt;br&gt;&lt;br&gt;</code>").</p>
  </blockquote>
  
  <p>Which option do I need to change to avoid this? I only want to change this control. Is it possible?</p>
