      function ClearAuthentication(LogOffPage) 
  {
     var IsInternetExplorer = false;    

     try
     {
         var agt=navigator.userAgent.toLowerCase();
         if (agt.indexOf("msie") != -1) { IsInternetExplorer = true; }
     }
     catch(e)
     {
         IsInternetExplorer = false;    
     };

     if (IsInternetExplorer) 
     {
        // Logoff Internet Explorer
        document.execCommand("ClearAuthenticationCache");
        window.location = LogOffPage;
     }
     else 
     {
        // Logoff every other browsers
    $.ajax({
         username: 'unknown',
         password: 'WrongPassword',
             url: './cgi-bin/PrimoCgi',
         type: 'GET',
         beforeSend: function(xhr)
                 {
            xhr.setRequestHeader("Authorization", "Basic AAAAAAAAAAAAAAAAAAA=");
         },

                 error: function(err)
                 {
                    window.location = LogOffPage;
             }
    });
     }
  }


  $(document).ready(function () 
  {
      $('#Btn1').click(function () 
      {
         // Call Clear Authentication 
         ClearAuthentication("force_logout.html"); 
      });
  });
