Abstract: In various embodiments, servers in a server pool share a centrally-generated encryption key that is used to encrypt session keys in tickets that can be used by client applications to share secure communication sessions across different servers belonging to the same server pools. When the client application first establishes a secure communication session with a server in a server pool, the server returns a ticket that includes an encrypted version of a session key generated using an encryption key shared by servers in the server pool. Thereafter, the client application can present the ticket to other servers in the server pool to restore the secure communication session with the other servers. Associations between servers and server pools can be communicated to the client application in any technically feasible manner, such as part of information indicating servers from which content can be accessed or via the Domain Name System (DNS).

Abstract: One embodiment of the present invention sets forth a technique for replicating a file within a network of servers. The technique includes determining one or more regional master servers included in a regional cluster of servers and causing each regional master server to retrieve a file from a fill source. The technique further includes, for at least one local cluster of servers included in the regional cluster of servers, determining one or more local master servers included in the at least one local cluster of servers, and causing each local master server to retrieve the file from one of the one or more regional master servers.
