NullRefrenceException was unhandled by user code
<p>Code below is placed in page_Load. How I should handle this to bypass UrlReferrer when you enter page directly first time and there is no referrer? 
What I am missing here?</p>

<pre><code>    if (HttpContext.Current.Request.UrlReferrer.AbsoluteUri != null)
    {
        urlReferer = HttpContext.Current.Request.UrlReferrer.AbsoluteUri.ToString();
    }
    else
    {
        urlReferer = "";
    }
</code></pre>
