Web Forms :: POST-ing To A Page And Loading That Page?

I'm using a form to POST credentials to a page. I'm able to POST my credentials to a page, but I'm stuck on trying to load that page that I POSTed my credentials to. In other words, the POST works, but the page doesn't then reload...here's a code snippet of what I'm running. I suspect I'm missing something and my knowledge of classes is limited so maybe it's a particular class I need to use.

HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";

[code]...
