- * File Uploads
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 <form> element temporarily modified to have its
- * target set to refer
- * to a dynamically generated, hidden <iframe> 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
- * "<" as "<", "&" as "&" 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
