Thanks for the info.
As another trial, I've attempted to use this in my views:
patch_vary_headers(response, ['Cookie'])
return response
The behavior is the same. Pages are not caching when this variance is
added. If I return all cache control back to the view, it works fine
again. What am I missing in being able to use URLConf for cache_page
control and add vary on cookie to the headers?
