title: How to use a web.config variable in an HTML header?
body: <p>I have this variable defined in my web.config file :</p>
  
  <pre><code>&lt;appSettings&gt;
      &lt;add key ="version" value="123"/&gt;
  &lt;/appSettings&gt;
  </code></pre>
  
  <p>and I am using it in my aspx pages' headers without problem:</p>
  
  <pre><code>&lt;link rel="stylesheet" type="text/css" href="../css/style.css?&lt;%= ConfigurationManager.AppSettings["version"] %&gt;"/&gt;
  </code></pre>
  
  <p>But this doesn't seem to work in a regular HTML page.
  What is the correct way of using a web.config variable in straight HTML ?</p>
