That depends. If the request does not include a content length header, then
FileUpload is working correctly. It cannot handle multipart requests unless
the content length is specified. There is an existing enhancement request to
add support for this case. However, this seldom comes up with browser

If the request _does_ include a content length header, then there might be
an issue. You should also ensure that the request has not already been
parsed by some other code before it reaches your code.
