My page redirect or transfer does not work?

For some reason, I've used Response.Redirect and also tried Server.Transfer but none of them work. I put this code in the Page_Load method but everytime the page, it does not get redirected or transfer to a new page.
 
protected void Page_Load(object sender, EventArgs e)
{
Server.Transfer("http://www3.mySite.com/newSite/NewPage/myNewPage.aspx");
}Any suggestion?
