I have a cookie which hold the information on which kind of navigation the user wants to see. The cookies is 'isotope-navigation' and it can hold either the value 'active' or 'inactive'.
Since the pages look quite different depending on the choice, I need to disable W3TC for one of those states. How can I do that? I have figured out that putting 'isotope-navigation' in the rejected cookie box turns off caching if that cookie is present, but I have no idea what the syntax is to disable it depending on a cookies value.
