+/* The idea of this "captcha" is to let the browser download an image that sets a cookie.
+Research showed that spam bots don't load images. You have to setup the cookie e.g. in the apache2
+configuration file. Here is an example where an image that's uploaded with mediawiki is used:
+
+<Directory /var/www/mediawiki/images/d/d0>
+    <Files "MyImage.png">
+        Header append Set-Cookie "mediawiki_token=%t; Path=/; HttpOnly"
+        ExpiresActive On
+        ExpiresDefault "access plus 5 second"
+    </Files>
+</Directory>
