Redirect HTTP traffic to HTTPS request on ELB

Question

I have a load balancer set to two of my ec2 instances. I would like to redirect all the HTTP traffic to HTTPS request on the load balancer. I'm using an Nginx server.

Change your server config file

if ($http_x_forwarded_proto = 'http') {
    return 301 https://yourdomain.com$request_uri;
}

ELB sets X-Forwarded-Proto header, you can use it to detect if the original request was to HTTP and redirect to HTTPS then.
