title: recaptcha makes calls over http rather than https
body: <p>I'm using recaptcha on my java jsp setup. I use the following code in my jsp</p>
  
  <pre><code>&lt;%@ page import="net.tanesha.recaptcha.ReCaptcha"%&gt;
  &lt;%@ page import="net.tanesha.recaptcha.ReCaptchaFactory"%&gt;
  
  
  &lt;%
  ReCaptcha c = ReCaptchaFactory.newReCaptcha("XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX", "XXXXXXXXXXXXXXXXXXX", false);
  out.print(c.createRecaptchaHtml(null, null));
  out.flush();
  %&gt;
  </code></pre>
  
  <p>However the site uses https so I'm getting an 'Only secure content is displayed' message on IE.</p>
  
  <p>If I look at the source recaptcha has generated the following</p>
  
  <pre><code>&lt;script type="text/javascript" src="http://api.recaptcha.net/challenge?k=XXXXXXXXXXXXXXXXXXXXXXX"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>How do I force recaptcha to use https and not http?</p>
