title: Liferay with SSL "XXX was loaded over HTTPS, but ran insecure content from XXX" issue
body: <p>We are trying to access Liferay with <code>https protocol</code>. We have apache in front of our liferay server.<br>
  We are able to access liferay with Https. When we navigate to any page and click on Configuration, configuration pop up opens. So far so good.<br>
  Now when we navigate to any page and keep browser ideal for some time and then click on configuration we get "ran insecure content" issue 
  <br>i.e <strong>The page at 'XYZ' was loaded over HTTPS, but ran insecure content from 'XYZ': this content should also be loaded over HTTPS</strong>. <br><br>
  I am wondering if we are missing any configuration that needs to be done with liferay and tomcat.<br>
  Same page loading works fine but after keeping it ideal for some time it gives this issue.</p>
  
  <p>Following configuration done with Liferay in portal-ext.properties:</p>
  
  <pre><code>web.server.protocol=https
  web.server.http.port=80
  web.server.https.port=443
  </code></pre>
  
  <p>Even tried by adding</p>
  
  <pre><code>company.security.auth.requires.https=true
  session.enable.phishing.protection=false
  </code></pre>
  
  <p>And with tomcat:</p>
  
  <pre><code>&lt;Connector port="8080" protocol="HTTP/1.1"
                  connectionTimeout="600000"
                  maxThreads="100" minSpareThreads="50" maxConnections="16384"
                  socketBuffer="-1" maxKeepAliveRequests="-1"
                  redirectPort="8443" URIEncoding="UTF-8" /&gt;
  </code></pre>
