Setting a Rule to Enable Rocket Loader

I would like to enable Rocket Loader for all pages on my website except the checkout page, which can be found at “”. I discovered that I can achieve this by configuring a rule, but it is not working as intended. The Rocket Loader continues to load on this page.

The expression I tried was:
(http.referer ne “/checkout”)

Why referer?

You need to create a rule looking at the Path: http.request.uri.path
