I approach Diaso after using collect.xdv lightly.
Usually in xdv I can use the nice env variable "HTTP_X_XDV" to allow the rendering of a specific css file (in portal_css via genericsetup). What could I use in diazo?
Thank's Vito
From the documentation of plone.app.theming you can use this:
request/HTTP_X_THEME_ENABLED | nothing
