Set multiple Environment variables in IISNode
<p>I understand I can use web.config.</p>

<pre><code>&lt;iisnode      
  node_env="production"
/&gt;
</code></pre>

<p>to specify one environmental <code>node_env</code> variable which could be accessed in server side *.js files via <code>process.env.node_env</code>.</p>

<p>However, for example I would like to have access to another environmental variable like 
<code>process.env.GLOBAL_PREFIX</code>. Similar scenarios like access to AWS credentials.  </p>

<p>When I tried </p>

<pre><code>&lt;iisnode      
  node_env="production"
  GLOBAL_PREFIX="somevalue"
/&gt;
</code></pre>

<p>, I could not get application running due to unrecognized web.config file.</p>
