| 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, |

---|
| 29 | * is they are <b>not</b> performed using XMLHttpRequests. Instead the form is submitted in the standard |

---|

---|
| 32 | * to a dynamically generated, hidden <tt><iframe></tt> which is inserted into the document |
---|
| 33 | * but removed after the return data has been gathered.</p> |
---|
| 34 | * <p>The server response is parsed by the browser to create the document for the IFRAME. If the |
---|

---|
| 38 | * <p>Characters which are significant to an HTML parser must be sent as HTML entities, so encode |
---|
| 39 | * "<" as "&lt;", "&" as "&amp;" etc.</p> |
---|
