We have a web app that works fine except we get the Security Information alert : The page contains both secure and nonsecure items. If you click on No, a couple of graphics don’t show up but the rest of the page is fine. What can we do to keep those alerts from popping up?
In a nutshell, it usually means that the person that wrote the page put in absolute references to graphics.
Also, since you are wrapping the site with SSL from the portal, the page it loading both SSL and non SSL HTTP requests.
