public string getPostBackStream(string rUrl)
{
// Create a new WebClient instance.
WebClient myWebClient = new WebClient();
// Create a new NameValueCollection instance to hold
// some custom parameters to be posted to the URL.
NameValueCollection myNameValueCollection = new NameValueCollection();
myNameValueCollection.Add("title","this is title"); 

myNameValueCollection.Add("excerpt","this is excerpt");
byte[] responseArray = myWebClient.UploadValues(rUrl,"POST",myNameValueCollection);
return Encoding.ASCII.GetString(responseArray);
