No, because your way of sending the file to the server does not match the \
Content-Type. A multipart/form-data content type implies that the body of your POST \
should look like a  MIME message, where each part has its own set of headers and a \
body. Here you are apparently just sending the file, as is.
It is a bit more complex than that.

Maybe search in Google for "ajax file upload" or something of the kind, to find a 
javascript library that would do that ?
