Answer 1

You should ensure that when the cookie is created (on the PHP site), the Set-Cookie header looks like this:

Set-Cookie: u=some_value; domain=example.com

Now you will be able to access this cookie from any subdomain on example.com. Inside the ASP.NET MVC application you can access it like this:

public ActionResult Index()
{
    var cookie = Request.Cookies["u"];
    ...
}
