I have content url - /content/myproject/products/product-one.html. I have created a vanity url such as - /content/product-one.html. When I access the page using dispatcher, page get cached for first time. Upon further access/request, auth checker validates for authorization and denies permission. Please see the log below.
Upon authorization denied, dispatcher look for content from publisher.
