I have very large website which uses a lot of cookies. There are approx. 14 different cookies are there. I have different cookies for each item. When a user surfs the site they will have 14 cookies in their browser. I do not want this.
I want a single cookie for my site that will have 14 items and I can add,edit and delete them. I tried many ways but I am not able to do this.
I need to put some run time cookies as well save the user name in cookie. After the user logs in I want to save their personal site address in it. Eventually I want both the user name and personal site address both. I want to save user name before and then when user goes to his personal site then i will store personal site name run time.
Does any one have an idea how I could do this?

Method 1
Matthew beat me to it, but yes, see the ASP.NET Cookies Overview…
To write and read a single cookie with multiple key/values, it would look something like this:
HttpCookie cookie = new HttpCookie("mybigcookie");
cookie.Values.Add("name", name);
cookie.Values.Add("address", address);
//get the values out
string name = Request.Cookies["mybigcookie"]["name"];
string address = Request.Cookies["mybigcookie"]["address"];
Method 2
There is a section in the ASP.NET Cookies Overview that discusses how to implement multiple name-value pairs (called subkeys) in a single cookie. I think this is what you mean.
The example from that page, in C#:
Response.Cookies["userInfo"]["userName"] = "patrick"; //userInfo is the cookie, userName is the subkey
Response.Cookies["userInfo"]["lastVisit"] = DateTime.Now.ToString(); //now lastVisit is the subkey
Response.Cookies["userInfo"].Expires = DateTime.Now.AddDays(1);
HttpCookie aCookie = new HttpCookie("userInfo");
aCookie.Values["userName"] = "patrick";
aCookie.Values["lastVisit"] = DateTime.Now.ToString();
aCookie.Expires = DateTime.Now.AddDays(1);
Response.Cookies.Add(aCookie);
EDIT: From the Cookies Overview (emphasis added):
Modifying and Deleting Cookies:
You
cannot directly modify a cookie.
Instead, changing a cookie consists of
creating a new cookie with new values
and then sending the cookie to the
browser to overwrite the old version
on the client.
