+</span> * @class Ext.data.Connection
+ * The Connection class encapsulates a connection to the page's originating domain, allowing requests to be made either
+ * to a configured URL, or to a URL specified at request time.
+ *
+ * Requests made by this class are asynchronous, and will return immediately. No data from the server will be available
+ * to the statement immediately following the {@link #request} call. To process returned data, use a success callback
+ * in the request options object, or an {@link #requestcomplete event listener}.
+ *
+ * <p><u>File Uploads</u></p>
+ *
+ * File uploads are not performed using normal "Ajax" techniques, that is they are not performed using XMLHttpRequests.
+ * Instead the form is submitted in the standard manner with the DOM &lt;form&gt; element temporarily modified to have its
+ * target set to refer to a dynamically generated, hidden &lt;iframe&gt; which is inserted into the document but removed
+ * after the return data has been gathered.
+ *
+ * The server response is parsed by the browser to create the document for the IFRAME. If the server is using JSON to
+ * send the return object, then the Content-Type header must be set to "text/html" in order to tell the browser to
+ * insert the text unchanged into the document body.
+ *
+ * Characters which are significant to an HTML parser must be sent as HTML entities, so encode "&lt;" as "&amp;lt;", "&amp;" as
+ * "&amp;amp;" etc.
+ *
+ * The response text is retrieved from the document, and a fake XMLHttpRequest object is created containing a
+ * responseText property in order to conform to the requirements of event handlers and callbacks.
+ *
+ * Be aware that file upload packets are sent with the content type multipart/form and some server technologies
+ * (notably JEE) may require some custom processing in order to retrieve parameter names and parameter values from the
+ * packet content.
+ *
+ * Also note that it's not possible to check the response code of the hidden iframe, so the success handler will ALWAYS fire.
