Cookies ... monster. Please help

Hi everyone,
Can someone tell me what's wrong with the way that i read a cookie as below:

private void Page_Load(object sender, System.EventArgs e)
{
Response.Cookies.Clear();
HttpCookie cookie = GetSessionCookie("MyCookie", "duh");
}

private HttpCookie GetSessionCookie(string cookieKey, string cookieValue)
{
HttpCookie cookie = Response.Cookies[cookieKey];
if (cookie == null)
{
cookie = this.CreateNewSessionCookie(cookieKey, cookieValue);
}
return cookie;
}

private HttpCookie CreateNewSessionCookie(string cookieKey, string
cookieValue)
{
HttpCookie cookie = new HttpCookie(cookieKey, cookieValue);
Request.Cookies.Add(cookie);
return cookie;
}

The problem is in GetSessionCookie(), after the line
HttpCookie cookie = Response.Cookies[cookieKey];
A new cookie with the specified key is added to the Request.Cookies
collection and the cookie object contains key "MyCookie" with empty value. As
a result, it never reaches the CreateNewSessionCookie() function call. What's
going on, please help me please, anyone?
My Web.Config file contains:
<authentication mode="Forms">
<forms name="MySettings" loginUrl="login.aspx" protection="All"
timeout="20" path="/"></forms>
</authentication>

Many thanks in advance.

For now I would say rather that you mixed up Response and Request. Try to
add the cookie to Response rather than Request...

Also you could use a property to expose the value stored by the cookie
wihtout having your page(s) knowing from where it comes...

Without the setting .Expires, the cookie is used only during the
current user session. T0 persist the cookie, set the .Expires property.
const string NAME_COOKIE = "TGWebMail";
Response.Cookies[NAME_COOKIE].Expires = DateTime.MaxValue;

Sample C# Code:
const stringNAME_COOKIE = "YourCookieName";
const stringNAME_USERID = "inpUserIDField";
const stringNAME_SERVER = "inpServerField";

private void Page_Load(object sender, System.EventArgs e)
{
// Retrieve settings from last visit
try
{
if (Request.Cookies != null)
{
inpUserID.Value =
Server.HtmlEncode(Request.Cookies[NAME_COOKIE][NAME_USERID]).ToString();
inpServer.Value =
Server.HtmlEncode(Request.Cookies[NAME_COOKIE][NAME_SERVER]).ToString();
}
}
catch {}
}

private void Submit_ServerClick(object sender, System.EventArgs e)
{
// Save user settings
try
{
Response.Cookies[NAME_COOKIE][NAME_USERID] = inpUserID.Value;
Response.Cookies[NAME_COOKIE][NAME_SERVER] = inpServer.Value;
Response.Cookies[NAME_COOKIE].Expires = DateTime.MaxValue;
}
catch {}

Thank you all for your replies. It was greatly appreciated. Yes, I was pretty
dumb getting mixed between Request & Response.
Another interesting finding : The new value of a cookie, after you update
it, does not "stick" until after the page has made its round trip to the
server! Is this by design??? Why can't we have a method like
"Cookies.Refresh()" or "Cookies.Update()" to register the new updated value
so that it can be used straight away?????
Cheers,
KD
