From: dhtml on 14 Jul 2008 13:08 Can't get my multipart/form-data processed. Error: "Stream ended unexpectedly" The post body is sent over XMLHttpRequest. (the submission works fine if sent via "normal" form submission). There seems to be a problem with the request. Bad headers, or content-length incorrect? I can't spot the error.
