need config help on f5

that script isn't available on the F5 if you didn't put it there. personally i would put it on an external linux box and not the big-ip. also the script was built for version 10, so it might be blindly work on version 11. but in principle if you don't have a lot of vips you can do rebuild them on the big-ip. you just have to understand well your cisco ace config and your big-ip config.

it helps if you can explain what that exactly does, most people here know F5 config, but less ACE config.

i did a short google search on this and seems to do something with conditional load balancing if the URL is either .* or /*, which to me feels like always, or are there cases load balancing should not happen on this vip?

if you do need something like this you can look at iRules or local traffic policies. both are able to add conditional load balancing.
