AJAX sending json data as text/xml
I have two sites using the same javascript code to interact with several web services. The code works perfectly in one site, but in the other, it is sending the data as text/xml. I have looked at the web config files in both sites and cannot spot anything that could cause the difference. The AjaxControlToolkit DLL files are the same. The AJAX call fails with an error 500 because the data is not in the proper form.
Code that makes the AJAX call:
function displaySessionNotifications() {
$.ajax({
type: "POST",
async: false,
url: "NotificationService.asmx/ListSessionNotifications",
contentType: "application/json; charset=utf-8",
dataType: "json",
data: JSON.stringify({}),
success: function (data) {
$list = JSON.parse(data.d);
if (window.console.log) { window.console.log('Notification Service Msg Cnt: ' + $list.length) };
for (var i = 0; i < $list.length; i++) {
displayMessage($list[i].MessageText, $list[i].MessageType, $list[i].IsSticky, $list[i].jGrowlClass, $list[i].ContainerId);
};
if ($list.length > 0) {
clearSessionNotifications($list[0].SessionId);
}
},
error: function (XMLHttpRequest, textStatus, errorThrown) {
alert("NotificationService/ListSessionNotifications failed: " + XMLHttpRequest.responseText);
}
});
}
Watch Data from Firebug:
this Object { url="NotificationService.asmx/ListSessionNotifications", global=true, type="POST", more...}
XMLHttpRequest
Object { readyState=4, status=0, statusText="error"}
