thanks for your response

now i see the problem. i just made a reload when i had a look at the 
header, my fault.
when i look at the header for the first request i get:

HTTP/1.x 200 OK

i think we could say this is the original question and your answer is 
what i expected.
so i think we should change the behavior of yanel.

does somebody knows what was the intention for the following code in 
YanelServlet:

                if (bytesRead == -1) {
                    String message = "InputStream of view does not seem 
to contain any data!";

                    Element exceptionElement = (Element) 
doc.getDocumentElement().appendChild(doc.createElementNS(NAMESPACE, 
"exception"));
                    
exceptionElement.appendChild(doc.createTextNode(message));
                    
response.setStatus(javax.servlet.http.HttpServletResponse.SC_INTERNAL_SERVER_ERROR);
                    setYanelOutput(request, response, doc);
                    return response;
                }

cheers
