Plugin is breaking varnish cache on pantheon

Hi,

It seems that this plugin is using the set cookie method or using sessions and is therefore breaking my varnish cache configuration on the pantheon platform. Here is more information from pantheon on how you can avoid this:

When I disable the plugin the issue goes away.

Please let me know if you need more information.

Thanks,

Nat
