What is the best way to identify logged user?
<p>I was looking for the efficient way to track the logged users when using <code>asp.net</code> <code>login control</code></p>

<pre><code>        if (!IsPostBack)
        {
            if (Membership.GetUser() != null)
            {
                var user = Membership.GetUser();
                Session["user"] = user;
            }
            else
            {
                Session["user"] = "";
            }
        }
</code></pre>

<p>Any suggestions will be appreciated </p>
