void Page_Load(Object Src, EventArgs E) {
myPage.Text = readHtmlPage("http://www.iwbuy.com");
}

private String readHtmlPage(string url)
{
String result;
WebResponse objResponse;
WebProxy proxyObject = new WebProxy("http://urproxy:port/",true);
WebRequest objRequest = System.Net.HttpWebRequest.Create(url);
objRequest.Proxy = proxyObject;

objResponse = objRequest.GetResponse();
using (StreamReader sr =
new StreamReader(objResponse.GetResponseStream()) )
{
result = sr.ReadToEnd();
// Close and clean up the StreamReader
sr.Close();
}
return result;
}
</script>
