20 | * <p>The class encapsulates a connection to the page's originating domain, allowing requests to be made |
---|
21 | * either to a configured URL, or to a URL specified at request time.</p> |
---|
22 | * <p>Requests made by this class are asynchronous, and will return immediately. No data from |
---|
23 | * the server will be available to the statement immediately following the {@link #request} call. |
---|
24 | * To process returned data, use a |
---|
25 | * <a href="#request-option-success" ext:member="request-option-success" ext:cls="Ext.data.Connection">success callback</a> |
---|
26 | * in the request options object, |
