which also work over HTTPS.

Nice article. I wish ELB supported IP address based stickiness, which would work over HTTPS.

@Rob Staveley,

You need to use an HTTP listener in order to be able to set up a session stickiness policy. Your elb-create-lb command should have “http” instead of “tcp”:

elb-create-lb c2 –availability-zones us-east-1a –listener “protocol=http, lb-port=80, instance-port=80″

Is the following a result of an Amazon service outage, or am I missing something?

>elb-create-lb c2 –availability-zones us-east-1a –listener “protocol=tcp, lb-port=80, instance-port=80″
DNS_NAME c2-588861184.us-east-1.elb.amazonaws.com

>elb-create-app-cookie-stickiness-policy c2 –cookie-name PHPSESSID –policy-name x
OK-Creating App Stickiness Policy

>elb-set-lb-policies-of-listener c2 –lb-port 80 –policy-names x
elb-set-lb-policies-of-listener: Service error: Policy [x] cannot be enabled for load balancer port [80] with
