[SOLVED] CloudFront CDN <> Amazon EC2 ProcessWire Issues in General Support Posted September 5 Hi poljpocket, thanks for your helpful and quick answer. It seems that the sessionFingerprint config is the "magic button" here. With fingerprinting false it's possible to login and do things in admin area. Even with HTTPS. That's a huge step forward. The PW config "HTTP hosts whitelist" includes just the main domain plus one dev subdomain. This config is fine. Okay, I think I've to test out the fingerprinting config details now. And to check out CloudFront differences. Can't still see user sessions in EC2 asssets. I think user sessions are stored in CloudFront. However, I hope my main issue is solved.
