Question

i think i am going a bit crazy, when i test this on my local webserver, it works fine
when i go out to the live website, it returns a blank string instead of the data i am expecting

i am not that familiar with C#, so i just wanted to check i am doing things right.
the data is just plain ascii text

 wc = new WebClient();
 wc.Headers.Add("Content-Type", "application/x-www-form-urlencoded");
 response = wc.UploadData(this.urlUpdate, Encoding.ASCII.GetBytes("data=" + HttpUtility.UrlEncode(buf.ToString())));

 s = Encoding.ASCII.GetString(response);

It really depends what you are trying to do… I’m not sure, for example, why you are url-encoding data in the body. An easier way to post key/value pairs is with UploadValues;

NameValueCollection inputs = new NameValueCollection();
string value = ...
inputs.Add("data", value);
webClient.UploadValues(address, inputs);
