Here's a simple static example: 


when LB_SELECTED {

You'll need to apply a server SSL profile to the VIP and turn it off in the iRule if the selected server's IP matches a non-SSL host. Also, depending on how many servers you have, it may also make sense to handle the SSL switching assignments in a data group.

ex.

10.70.0.1 := off

10.70.0.2 := on

10.70.0.3 := on
