Below is a PHP example to do the same thing:


+$callback = $_REQUEST['callback'];
+
+// Create the output object.
+$output = array('a' => 'Apple', 'b' => 'Banana');
+
+//start output
+if ($callback) {
+    header('Content-Type: text/javascript');

+} else {
+    header('Content-Type: application/x-json');
+    echo json_encode($output);
+}

Below is the ASP.Net code to do the same thing:


+String jsonString = "{success: true}";
+String cb = Request.Params.Get("callback");
+String responseString = "";
+if (!String.IsNullOrEmpty(cb)) {
+    responseString = cb + "(" + jsonString + ")";
+} else {

+Response.Write(responseString);
