Yes but when we receive request it is not from the end user but other host. For eg:
User -> server A (prepares file) -> (http request that need load balancing) Our host So it's server A actually making the request not the user but we need to load balance user because this user can sign off and connect again to server B. And if server B connects to other data center before file is replicated then that will be a problem.
