Thanks so much for that...
I found out I have mixture of different LTMs (different ones for different locations based on when they where purchased). So basically I have LTM 6400 v9.2.3 and LTM 6900 V10.2.0. Would the older versions need updating?
So what you are saying is that I don't need the APM to do this, just create an irule? I assume if I did use the APM (apart from other functionality and benefits an APM provides) would it provide a graphical interface to do this type of stuff.
Many thanks for your time.
