File upload and Progress events with HTML5 XmlHttpRequest Level 2

The XmlHttpRequest Level 2 specification adds several enhancements to the XmlHttpRequest object. Last week I had blogged about cross-origin-requests and how it is different from Flash\Silverlight's approach .  With Level 2 specification one can upload the file to the server by passing the file object to the send method. In this post I'll try to explore uploading file using XmlHttpRequest 2 in conjunction with the progress events. I'll also provide a description on the new HTML5 tag -  progress which can be updated while the file is being uploaded to the server.
