What is the Java Cache?

After you install the latest image on the ProxySG or if you experience problems using the Director Management Console, Blue Coat recommends clearing your computer's Java cache. Clearing the browser cache triggers a reload of the Java Archive (JAR) files. This reloading prevents Java exception errors on the Web browser when you access the ProxySG Management Console.

You might also need to clear the Java cache after you rollback to SGME 5.4.2.4 from a later release due to the fact Director .jar files might be updated in later releases.

For more information about the Java Control Panel, which enables you to clear the Java cache, see http://java.sun.com/javase/6/docs/technotes/guides/deployment/deployment-guide/jcp.html
