Thanks for reply, I have done the same workaround -> since could not find better one, but unfortunately If remote host replies to ping does not mean, that remote webserver is running  

I have been bothering with this same issue for couple of hours with no result. I want to log to my local PHP webservice (which is deliberately offline for testing purposes) unfortunately Netduino does not throw timeout exception, but it hangs on this line even though timeout is set to 5000 ms.

HttpWebResponse response = (HttpWebResponse) webrequest.GetResponse();

I include my piece of code:

 try
            {
                if (_isNetworkAvailable)
                {
                    HttpWebRequest webrequest = (HttpWebRequest) HttpWebRequest.Create("http://" + server + url);
                    webrequest.Method = "GET";
                    webrequest.Timeout = 5000;
                    webrequest.KeepAlive = false;
                        
                    HttpWebResponse response = (HttpWebResponse) webrequest.GetResponse();
                    if (response.StatusCode == HttpStatusCode.OK)
                    {
                        using (var reader = new StreamReader(response.GetResponseStream()))
                        {
                            var buffer = new char[5];
                            var builder = new StringBuilder();
                            while (reader.Read(buffer, 0, 5) > 0)
                                builder.Append(buffer);

                            reader.Close();
                            reader.Dispose();
                            response.Close();
                            response.Dispose();
                  
                            return builder.ToString();
                        }
                    }
                    else { return null; }

                }
                else {
                    throw new Exception("Network cable unavailable");
                }
            }
            catch (WebException e)
            {                
                if (e.Status == WebExceptionStatus.ProtocolError)
                {
                    
                }
                return null;
            }
            catch(Exception ex) {
                Debug.Print(ex.Message);
                return null; 
            }

I would also join to whitecap's question:

Is there any way to use the netmf_toolbox_http_client with a timeout (like httpWebRequest)? If the site does not respond the client appears to wait indefinitely.  

Thanks

Did you anyhow found out how to decode data from Oregon wireless temp sensor?
