A method of providing access to data via a public communications network includes the receiving a first data session request having a storage group mark, the storage group mark defining a server storage group, a load balancer route the request to a first server that processes request and any related session information, storing any altered first session data in a data storage. The load balancer receives a second request, wherein the second request also has the same storage group mark. The load balance selects a second server to respond to the second request. As before, the second server processes the second request and the altered first session data loaded from the data storage. After processing, the second server stores any altered second session data in the stored data on the first server as well as the second server and returns the altered second session data.
