Question

I have 2 website on my IIS7, I can put the same domain for both of them, I want some cookies of both applications to be shared between them, so than I can create the cookie from one of them and read it from the other one, is that possible? do I need any custom configurations to do that?

note: My websites, 1 is asp.net forms website and the other is MVC.

When you create the cookie specify the domain:

var cookie = new HttpCookie("foo", "bar")
{
    // indicates that only server side scripts can read this cookie
    HttpOnly = true,

    // indicates that the cookie will be available throughout the entire domain
    Domain = "example.com"
};
Response.AppendCookie(cookie);

Now on the other application you will be able to access this cookie (assuming of course it is running on the same domain):

var cookie = Request.Cookies["foo"];
