Digest authentication exception

The body in the 401 response is not read which makes the authentication to fail, I get the exception ("No colon found.", "header").

If I read the body after the header in the method WsStream::ReadHandshake then it works fine.

if (_innerStream.ReadByte().EqualsWith('\r', add) &&
_innerStream.ReadByte().EqualsWith('\n', add) &&
_innerStream.ReadByte().EqualsWith('\r', add) &&
_innerStream.ReadByte().EqualsWith('\n', add))
{
string tempRes = Encoding.UTF8.GetString(buffer.ToArray());
var clStartIndex = tempRes.IndexOf("Content-Length:");
if (-1 != clStartIndex)
{
clStartIndex += ("Content-Length:".Length + 1);
int crIndex = tempRes.IndexOf('\r', clStartIndex);
string contentLenStr = tempRes.Substring(clStartIndex, crIndex - clStartIndex);
int contentLen = Convert.ToInt32(contentLenStr);
for (int i = 0; i < contentLen; ++i)
{
_innerStream.ReadByte();
}
}

    read = true;
    break;

}

Start in WsStream::ReadHandshake and reproduce the digest-authentication failure for a 401 response. Trace how the response header and Content-Length are handled, then verify that the response body is consumed before authentication parsing and that the "No colon found." exception no longer occurs.
