  I am posting XML file to Web services using C# , but I am getting error when I am requesting the response 'Server Error - 500 - You are not allowed to access the system . Any help will be appreciated.

  protected void Page_Load(object sender, EventArgs e)

  {

  WebRequest req = null;

  WebResponse rsp = null;

  try

  {

  string fileName = Server.MapPath("~\\test.xml");

  string uri = "http://212.170.239.71/appservices/http/FrontendService";

  req = WebRequest.Create(uri);

  //req.Proxy = WebProxy.GetDefaultProxy(); // Enable if using proxy

  req.Credentials = new NetworkCredential("myusername", "mypassword");

  req.Method = "POST"; // Post method

  req.ContentType = "text/xml"; // content type

  // Wrap the request stream with a text-based writer

  StreamWriter writer = new StreamWriter(req.GetRequestStream());

  // Write the XML text into the stream

  writer.WriteLine(this.GetTextFromXMLFile(fileName));

  writer.Close();

  // Send the data to the webserver

  rsp = req.GetResponse(); //I am getting error over here

  StreamReader sr = new StreamReader(rsp.GetResponseStream());

  string result = sr.ReadToEnd();

  sr.Close();

  Response.Write(result);

  }

  catch (WebException webEx)

  {

  Response.Write(webEx.Message.ToString());

  Response.Write(webEx.StackTrace.ToString());

  }

  catch (Exception ex)

  {

  Response.Write(ex.Message.ToString());

  Response.Write(ex.StackTrace.ToString());

  }

  finally

  {

  if (req != null) req.GetRequestStream().Close();

  if (rsp != null) rsp.GetResponseStream().Close();

  }

  }

  //Function to read xml data from local system

  private string GetTextFromXMLFile(string file)

  {

  StreamReader reader = new StreamReader(file);

  string ret = reader.ReadToEnd();

  reader.Close();

  return ret;
