Api client that fetches global configuration from web.config
<p>In my application I want to do something like:</p>

<pre><code>SomeApiClient apiClient = new SomeApiClient();

List&lt;User&gt; apiClient.getUsers();
</code></pre>

<p>In my web.config, I will a few configuration key/value pairs.</p>

<p><strong>How can I write the constructor of SomeApiClient in such a way that it loads the values from the web.config, but not each time, only once when the application starts or first request?</strong></p>
