I will try to configure ISS 10.0 with cloudflare using SSL and Authenticated Origin Pulls but it is immposible. When i use only SSL without Authenticated Origin Pulls everything works fine. When i disable anonymous authentication everything stop working. When i access the site with cloudflare always I revice a HTTP Error 401.2 - Unauthorized You are not authorized to view this page due to invalid authentication headers. I will try to configure it using this,but it not working. Maybe someone can help me to reslove the issue?
