Due to various browser
limitations, this message can
mean either (a) the server URL
was invalid, did not respond, or
returned an HTTP error code; or
(b) the server request succeeded
but the response was 0 bytes of
data. To work around this
restriction, design your
application so that the server
never returns 0 bytes of data. If
you receive the fault code
XMLConnector.No.Data.Received
you will know that there was a
server error, and can inform the
user accordingly.
