State Management :: Set Session Using Cookies?

i have 3 pages, lets say pageA, pageB and pageC.

1 . From "pageB", i'm sending some data to "pageA" and and retriving the result with using HTTPWebRequest and HTTPWebResponse classes. I have no problem with this

2. pageA fills some session data, like Session["CustomerInfo"] .

3. After retrving some data from "pageA", I'm redirecting from "pageB" to "pageC".

At PageC, i want to use session variables which i fill at "pageA":

At pageB, i get the CookieContainer of the HTTPWebRequest object and it retrives correct SessionId.

And here is the code that redirects pageB to pageC:

Response.Cookies.Clear();
Request.Cookies.Clear();
foreach (Cookie cookie in SessionCookieContainer.GetCookies(new Uri(http://localhost/bla/bla)))
{
Response.Cookies.Add(new HttpCookie(cookie.Name, cookie.Value));
Request.Cookies.Add(new HttpCookie(cookie.Name, cookie.Value));
}
//Response.Redirect("../Default.aspx");
Server.Transfer("../Default.aspx",true);

At pageC , Request.Cookies and Response.Cookies are set truly, as i sent them from pageB, but there is nothing in the session. Session.Count is zero. And SessionId is different from the value which is stored in cookies.
