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.
