If you have worked on 126.96.36.199 and 188.8.131.52, you must be familiar with the Manifest files. We had manifest ,custom manifest and manifestextension.map files. These files sieze to exist from 184.108.40.206 onwards!!
Instead of these manifest files, we have a better way of maintaining them. So Just navigate to : Administration – Application >> Manifest Adminstration and add the Applet and the corresponding JS File details.
Before this you need to register the JS under : Administration – Application >> Manifest Files
