Communication session resumption

A system that at least:

• as a result of receiving, at a first server, from a client computer, a request to establish a cryptographically protecte communication session with the first server in accordance with a first set of session parameters, obtains a list of servers at the client computer from the first server that identifies a plurality of servers with which the cryptographically protected communication session may be resumed, wherein the first set of session parameters includes a cryptographic key and is associated with the list of servers;
• receives, at a second server in the list of servers, from the client computer, another request to establish another communication session with the second server;
• and
• based at least on the other request, establishes the other communication session between the second server and the client computer in accordance with a second set of session parameters, the second set of session parameters based at least in part on the first set of session parameters, wherein the other communication session enables data to be communicated between the second server and the client computer using at least the cryptographic key of the first set of session parameters.

A computer-implemented method comprising:

• as a result of receiving, from a client computer system, a request to establish a communication session and a handshake being initiated between the client computer system and a server providing to the client computer system, a list of servers that indicates a plurality of servers with which another communication session may be established;
• receiving, from the client computer system, another request to establish another communication session;
• storing a first set of session parameters associated with the communication session, wherein the first set of session parameters includes at least a cryptographic key or a cipher suite and is determined at least in part by the handshake between the client computer and the server;
• obtaining the cryptographic key or the cipher suite from the stored first set of session parameters as a result of receiving the other request;
• and
• establishing a cryptographically protected communication session based on the other request, the cryptographically protected communication session allowing exchange of cryptographically protected data between the client computer and the server based at least in part on the cryptographic key or the cipher suite of the first set of session parameters.
