****************************************************************
At the end of a POST request, WebSphere attempts to read
from the client any remaining POST data that was sent by
the client.  If an IOException occurs during the reading
of the POST data (when parsing the original POST data),
WebSphere should not attempt to read the POST data again since
the client socket is no longer accessible to read data from.
Problem conclusion
Modified the code to limit the possibility of this IOException
from occurring.  WebSphere will now track if an IOException
occurs when reading in the original POST data and not try
to read from the socket when this occurs.
