Static (ok, possibly not always static) images, load balancing done on client side with possible error handling. I think this is best solution, that can be done in this place - static file serving. But, when you serving main request (when user request dynamically generated content - HTML page) for user you can't trust this solution. When load balancing is done by NGINX (and, as I remember Lighttpd) - if one of servers do not answer in correct time request will be sent to other server - user will get answer any way, because there are mo than 1 server for user, but user don't see them. And when load balancing done with "other subdomain" if this domain fails - user sees nothing. Also, ServerSide load balancing can be done in Hash mode and in right place with right solution this coud be very effective solution. Good solution in right place.
