Javascript file - change source at runtime from web.config
<p>I have this in my code:</p>

<pre><code>&lt;script type="text/javascript"
  src="path?key=1234567890"&gt;
&lt;/script&gt;
</code></pre>

<p>I added this in web.config:</p>

<pre><code>&lt;appSettings&gt;
    &lt;add key="key" value="1234567890"/&gt;
</code></pre>

<p></p>

<p>How to implement it in the above code?</p>
