why do we use HttpContext.Current?
<p>i don't know, why do we use HttpContext.Current?<br />
in this property i use it for Session but i don't know why! </p>

<pre><code>public static string Name
{
    get
    {
         if (HttpContext.Current.Session["_n_"] != null)
            return HttpContext.Current.Session["_n_"].ToString();
         else return "";
    }
    set
    {
         HttpContext.Current.Session["_n_"] = value;
    }
}
</code></pre>
