title: How to remove "Microsoft-HTTPAPI/2.0" from http response header on App Service Web App
body: <p>I have created two asp.net + MVC applications and deployed one to Azure App Service web app and other into an app service web application created in a ASE (Application Service Environment). </p>
  
  <p>When providing special characters in the URL the response header consists of "Microsoft-HTTPAPI/2.0". I have done the below changes in the application but the issue still persists. </p>
  
  <pre><code>&lt;security&gt;
    &lt;requestFiltering removeServerHeader="true"/&gt;
  &lt;/security&gt;
  
  protected void Application_PreSendRequestHeaders(Object source, EventArgs e)
  {
      HttpContext.Current.Response.Headers.Remove("Server");
  }
  </code></pre>
