Override single attribute in machine.config
<p>I was wondering if it's possible to override just an attribute of a tag in machine.config ?</p>

<p>More exactly I want to set the domain attribute of  in machine.config, as it differs from my production server and my development server.</p>

<p>I tried just adding the tag to machine.config, but alas it doesn't seem to have an effect.</p>

<p>in machine.config I added:</p>

<pre><code>&lt;authentication&gt;
  &lt;forms domain=".foo.com" /&gt;
&lt;/authenticaion&gt;
</code></pre>

<p>EDIT:</p>

<p>Since web.config overrides machine.config, the question is rather how I avoid losing my domain attribute on the  tag, when forms is also defined in web.config ?</p>
