You can create a cookie (that will expire when the browser closed) to identify the first visit, and a never expire cookie to identify the visited user.

sample demo

// You need to call this code from all pages
protected void Page_Load(object sender, EventArgs e)
if (Request.Cookies["visited"] == null && Request.Cookies["firstVisit"] == null)
// Will expire when the browser closed
HttpCookie firstVisit = new HttpCookie("firstVisit", "true");

// Never expire cookie flag
HttpCookie visited = new HttpCookie("visited", "true");
visited.Expires = DateTime.Now.AddYears(100);

// Detect status
if (Request.Cookies["firstVisit"] != null)
Response.Write("You are now in the first visit.<br />");
Response.Write("You have visited this site last time.<br />");
