+<p>When <code class="docutils literal"><span class="pre">$config['base_url']</span></code> is not set, CodeIgniter tries to automatically
+detect what your website’s base URL is. This is done purely for convenience
+when you are starting development of a new application.</p>
+<p>Auto-detection is never reliable and also has security implications, which
+is why you should <strong>always</strong> have it manually configured!</p>
+<p>One of the changes in CodeIgniter 3.0.3 is how this auto-detection works,
+and more specifically it now falls back to the server’s IP address instead
+of the hostname requested by the client. Therefore, if you’ve ever relied
+on auto-detection, it will change how your website works now.</p>
+<p>In case you need to allow e.g. multiple domains, or both <a class="reference external" href="http://">http://</a> and
+<a class="reference external" href="https://">https://</a> prefixes to be dynamically used depending on the request,
+remember that <em>application/config/config.php</em> is still a PHP script, in
+which you can create this logic with a few lines of code. For example:</p>
