On each new page view the xf_session cookie changes. Within the admin area the xf_admin cookie changes randomly, at the public area the xf_admin cookie does not change. The cookie xf_user always stays the same. The community is behind Amazon Cloudfront which lets all cookies and headers through. When accessing the server without the CDN directly all cookies stay the same after each page view. Do you know what triggers the xf_session change? Thanks!
