I want to use distributed cluster configured like: xx.resource.server.com. xx - can be anything from aa to zz, most of the requests will be one time.
I need the connection to be secure between client and server, so I was thinking of using multidomain SSL certificate, to be safe from ears dropper, but from my understanding this would require establishing SSL connection on every request, which is costly and inefficient.
Is there an effective way to share SSL established key for aa.resource.server.com and ab.resource.server.com? Is it better, just to use shared key, established with SSL protected server?
