Under what circumstances might not be viewstate persisted?
<p>I have a page and a user control inside it. </p>

<p>I assign a value to viewstate in the control and do </p>

<pre><code>Server.Transfer(Request.Url.AbsolutePath);
</code></pre>

<p>but when I check the value on control's Page_Load() event the assigned value doesn't exists (viewstate is empty, has not keys).</p>

<p>Why might this happened?</p>
