JavaScript Engine Updates

Overview: Updating the JavaScript engine

The BIG-IP® system provides an option for updating the JavaScript engine, which improves client-side functionality and enhances protection of your
BIG-IP®DataSafe
profile. In the Engine Updates screen you can choose to download and install an engine update from the Update server when it is available, or perform a manual installation of an engine update from an update file you receive from F5.
Once daily, the BIG-IP system determines if engine updates are available from the Update server. If so, the system notifies you in the status area of the screen.
If you are working with a group of BIG-IP systems that are in a trust domain and an update is performed on one of the BIG-IP systems in that group, all the other systems in that group are simultaneously updated as well.

Updating the JavaScript engine

Updating the JavaScript engine enables the BIG-IP® system to discover new types of generic malware.
