Why we can't use Response.Write on Page_Unload Event?
<p>I am using <code>Respose.Write</code> on  <code>Page_Unload</code> event, then I get the error </p>

<blockquote>
  <p>Response is not available in this context.</p>
</blockquote>

<p>May I know why we can't use? </p>

<pre><code>protected void Page_Unload(object sender, System.EventArgs e)
{
  Response.Write(" hi ");
}
</code></pre>
