title: Ajax call not working in IE 11 only
body: <p>I have build a web application.It is working fine on every browser(Chrom,firefix,IE 7,8,9,10) but not 11 only.</p>
  
  <p>here is the html :</p>
  
  <pre><code>&lt;div class="menu_nav"&gt;
                  &lt;ul&gt;
                      &lt;li&gt;&lt;a href="Upload.aspx"&gt;Upload&lt;/a&gt;&lt;/li&gt;
                      &lt;li class="active"&gt;&lt;a id="btnSignIn" runat="server" rel="#div_Overlay" href="#"&gt;Sign in&lt;/a&gt;&lt;/li&gt;
                  &lt;/ul&gt;
              &lt;/div&gt;
  </code></pre>
  
  <p>here is overlay div code:</p>
  
  <pre><code>$("#btnSignIn").overlay({
  
          //    // some mask tweaks suitable for modal dialogs
          //    mask: {
          //        color: '#ebecff',
          //        loadSpeed: 200,
          //        opacity: 0.9
          //    },
          //    //effect: 'myEffect',
          //    closeOnClick: false,
          //});
  </code></pre>
  
  <p>Here is my ajax request:</p>
  
  <pre><code>$("#btnLogin").live('click', function () {
          if ($("#txtUserId").val() == "") {
              alert("User Id Required");
          }
          else if ($("#txtPassword").val() == "") {
              alert("Password Required");
          }
          else {
              $.ajax({
                  url: "MainPage.aspx/CheckLogin",
                  data: "{'UserId':'" + $("#txtUserId").val().trim() + "','Password':'" + $("#txtPassword").val().trim() + "'}",
                  type: "POST",
                  contentType: "application/json; charset=utf-8",
                  dataType: "json",
                  success: function (data) {
                      data = JSON &amp;&amp; JSON.parse(data.d) || $.parseJSON(data.d);
                      if (data.Table[0].IsAllowed == "1") {
                          $("#btnSignIn").hide(function () {
                              var lblUserName = "&lt;label class='lblWelcome'&gt;Welcome, " + data.Table[0].UserFirstName + "&lt;a id='btnlogout' href='#'&gt;logout&lt;/label&gt;";
                              $("#btnSignIn").parent().append(lblUserName);
                              $("#btnSignIn").overlay().close();
                          });
                          var v = window.location.search.replace("&amp;msg=%27not%20logged%20in%27", "");
                          window.location.search = v;
                      }
                      else {
                          if (data.Table[0].IsVerified == "NotVerified") {
                              $("#txtPassword").val("");
                              $("#tr_Verify").show();
                          }
                          else {
                              $("#txtUserId").val("");
                              $("#txtPassword").val("");
                              alert("User Id Or Password Incorrect");
                          }
                      }
  
                  },
                  error: function (err) {
                      alert("Some error occured.Please contact to your administrator." + err);
                  }
              });
          }
          return false;
      });

  <pre><code>error:function(xhr,err,exception){
      alert(xhr); //shows [object][object]
      alert(err);    //shows error
      alert(exception); //shows Internal server error
      });
  </code></pre>
