dear all..

i am connecting to a web service to get a specific results and my windows applications download many files according to response from web-service

the problem appears only when using a proxy in my internet explorer using program "analog proxy"
this is the steps i made:
Code:
tools->internet options->connections->Lan settings-> and i checked use proxy server for Lan..... with address: 192.168.1.240 and port:6588


my code to connect to web-service is:
Code:

            HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://www.o-survey.com");

            IWebProxy proxy = request.Proxy;
            if (proxy != null)
            {
                MessageBox.Show("Proxy: {0}"+ proxy.GetProxy(request.RequestUri));
            }
            else
            {
                MessageBox.Show("Proxy: {0}Proxy is null; no proxy will be used");
            }

            WebProxy myProxy = new WebProxy();
            Uri newUri = new Uri("http://162.168.1.240:6588");
            // Associate the newUri object to 'myProxy' object so that new myProxy settings can be set.
            myProxy.Address = newUri;
            // Create a NetworkCredential object and associate it with the 
            // Proxy property of request object.
            myProxy.Credentials = new NetworkCredential("john", "johngra");
            request.Proxy = myProxy;

and in app.config i put the following line
Code:
  <system.net>

    <defaultProxy enabled="true" useDefaultCredentials="true" >
    </defaultProxy>
    
  </system.net>
i got this error:
