asp.net viewstate data
<p>I'm using asp.net 4. Every control on a page has its viewstate turned off and in the HTML output, the viewstate looks like this:</p>

<pre><code>&lt; input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE"
value="/wEPDwULLTEwNDk4OTMyNTZkZGfL5BMyxxloFnGh0LG4Z2Wef3pPOstqLKsp8DrWelqn" /&gt;
</code></pre>

<p>When I run this string in a Base64 decoder I see that it's equal to -1049893256. This number changes on every page and every request.</p>

<p>The only controls I'm using are essentially literals; the page is in a master page.</p>

<p>What could this be field represent?</p>
