Hi Neil O - Can you clarify a bit more about what you're looking to change or how it is configured today?
Are you using SSL today between the web app and the cache and EAE nodes, which you're looking to turn off? I'm doing some research on my side but wanted to get a better understanding of exactly what your set up looks like.
I was just advised that we have a dedicated, private support group. i will be adding this issue there.
