  <p>Till now I've tried following options,</p>
  
  <pre><code> &lt;httpRuntime targetFramework="4.5" requestValidationMode="2.0" /&gt;
   &lt;pages validateRequest="false" enableEventValidation="false"&gt;&lt;/pages&gt;
  </code></pre>
  
  <p>FYI, its working fine in local, but when I deploy it on server its not working properly,
  Do I need to work on something at IIS ?</p>
