[cfaussie] Session Sharing on Cloud Cluster
So RackSpace and Amazon dont support sticky sessions on https, im guessing because the data is encrypted and they cant see it. I was toying with the idea of doing something like this, which would effectivally do the same thing Lets say I have 4 endpoints ap00 (balancer) ap01 (server 1) ap02 (server 2) ap03 (server 3) In on request if the server is ap00, just redirect to the real server im on, which I can obtain (answer to previous question) machineName = createObject(java, java.net.InetAddress).localhost.getCanonicalHostName(); so balancer takes me to 03, I just hard redirect to 03 and user stays on that server. Only downside I can think of, which is a decent downside, is that if a user bookmarks any url, they are on that server forever. Any other options, I cant be the first person to try this.

Re: [cfaussie] Session Sharing on Cloud Cluster
Dale The other way to tackle this would be to run your own dedicated load-balancer on your ap00 instance. Your SSL certs would live on ap00 which could then handle the SSL connections and manage the sticky sessions to your actual application servers. This would remove the need for CF to actually know anything about how your app is deployed across the cloud.

Re: [cfaussie] Session Sharing on Cloud Cluster
I'd be surprised if you can't install a SSL cirt on the load balancer. This article seams to indicate it is possible at Amazon: http://awsdocs.s3.amazonaws.com/ElasticLoadBalancing/latest/elb-dg.pdf Paul.

Any recommendations, I was also looking for a third party SSL load balancer service if anyone knows of such a thing.

RE: [cfaussie] Session Sharing on Cloud Cluster
Yes, I found that afterwards with Amazon, most don't support it. I'd be happy with IP based server allocation.

Re: [cfaussie] Session Sharing on Cloud Cluster
Hi Dale, what's the code like? One option is to not use the session scope and go to client vars.

Re: [cfaussie] Session Sharing on Cloud Cluster
What about turning on JSessionIDs, and use a distributed cache to store session information in. CF sets up the unique IDs for you, and you just use that value to store data in your distributed cache. Then it doesn't matter what server you are on. Amazon has ElastiCache - should be easy enough to get going.

Here's a URL to try; https://mrbuzzy.jelastic.com/balance/ It will out put various things for debugging, try it from more than one browser, machine, device, etc. Your HTTPS request will hit and 'stick' on a particular host. It looks like Nginx is handling the SSL decryption and 'stickiness' to one of many hosts. It also uses Tomcat clustering an session replication. The 'node' within the Tomcat cluster can be seen in the JSESSIONID which is used for 'stickiness' at the Tomcat level. ColdFusion is seeing a non-SSL request on port 80. Also attaching a few screenshots. Cheers.
