</span> * @class Ext.Ajax
 * @singleton
 * @markdown

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 by 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.
