Using C#.net update google fusion tables automatically!

Dear Björn Ranft,

Please say whats the wrong in my code?
I know that points but my code says "Timeout".
See my code,
string UserName = Convert.ToString(ConfigurationManager.AppSettings["proxyUserName"]);
string Password = Convert.ToString(ConfigurationManager.AppSettings["proxyPassword"]);

protected void Page_Load(object sender, EventArgs e)
{
//val = "https://www.google.com/fusiontables/api/query/?sql=SELECT%20*%20FROM%203602788";
//reqIcon = WebRequest.Create(val);
//if (UserName != string.Empty && Password != string.Empty)
// reqIcon.Proxy.Credentials = new System.Net.NetworkCredential(UserName, Password);
//resIcon = reqIcon.GetResponse();

// Get the authentication token to use on all requests

string email = "rameshangler@gmail.com";
string password = "ramesh22";
string token = getAuthToken(email, password);

//// Example of an insert query
//string result1 = executeUpdate("insert into tableid ('column 1','column 2') values ('value 1', 'value 2')", token);

// Example of a select query, should return the newly inserted row in the previous statement
string result2 = executeSelect("select * from 203602788", token);

// Show the result in the label
//lblMessage.Text = result1 + "||" + result2;
lblMessage.Text = result2;

* credentials for a given user.
