title: internal link - jump to link - from https to http issue
body: <p>I did a home-page in php (which can be seen only on https) that page relinks to 2 different internal webportal.
  One of the two internal webportal (MpcPanel) is on a http url.</p>
  
  <p><strong>example:</strong>
  home-page url: <code>https://192.168.1.100</code></p>
  
  <p>html code of the home-page that does not link to the correct wepportal (MpcPanel):</p>
  
  <pre><code>  &lt;div align="center" class="copyright" style="width: 400px; border: thin solid #F48C13; margin:0 auto;"&gt;
      &lt;p&gt;&lt;a href="/cgi-bin/class/login.cgi"&gt;&lt;strong&gt;Accesso a MpcPanel&lt;/strong&gt;&lt;/a&gt;&lt;/p&gt;
    &lt;p&gt;&lt;a href="/cgi-bin/class/login.cgi"&gt;&lt;img src="/classpba/include/images/logo.png" alt="" width="240" height="50" longdesc="/classpba/include/images/logo.png" /&gt;&lt;/a&gt;&lt;/p&gt;
  </code></pre>
  
  <p>The full url I want to go is: <code>http://192.168.1.100/cgi-bin/class/login.cgi</code></p>
  
  <p>And the full url of the image is: <code>http://192.168.1.100/classpba/include/images/logo.png</code></p>
  
  <p>I dont want to put in the <em>src=</em> the full url becouse, I want the opportunity to change the IP of my server without having to be forced to manually change also the IP in the home-page.</p>
