I'm trying to move my SignalR application, hosted in AWS behind an ELB on IIS8, to use websockets.
After following the steps recommended by AWS (change listeners on the ELB to TCP, enable proxy protocol - http://docs.aws.amazon.com/ElasticLoadBalancing/latest/DeveloperGuide/enable-proxy-protocol.html) I'm unable to find a way of getting IIS to understand the proxy protocol information, and get bad requests instead.
Has anyone been successful in getting websockets through an AWS ELB and IIS working?
