+/**
+ * @class Ext.Ajax
+ * @singleton
+ * @markdown
+ * @extends Ext.data.Connection
+
+A singleton instance of an {@link Ext.data.Connection}. This class
+is used to communicate with your server side code. It can be used as follows:
+
+    Ext.Ajax.request({
+        url: 'page.php',
+        params: {
+            id: 1
+        },
+        success: function(response){
+            var text = response.responseText;
+            // process server response here
+        }
+    });
+
+Default options for all requests can be set be changing a property on the Ext.Ajax class:
+
+    Ext.Ajax.timeout = 60000; // 60 seconds
+
+Any options specified in the request method for the Ajax request will override any
+defaults set on the Ext.Ajax class. In the code sample below, the timeout for the
+request will be 60 seconds.
+
+    Ext.Ajax.timeout = 120000; // 120 seconds
+    Ext.Ajax.request({
+        url: 'page.aspx',
+        timeout: 60000
+    });
+
+In general, this class will be used for all Ajax requests in your application.
+The main reason for creating a separate {@link Ext.data.Connection} is for a
+series of requests that share common settings that are different to all other
+requests in the application.
