Abstract: A server establishes a secure session with a client device where a private key used in the handshake is stored in a different server. An encrypted connection is established between the first server and the second server. A message is received from the client device that initiates a procedure to establish the secure session between the client device and the first server. As part of this procedure, the first server transmits over the encrypted connection a request to the second server to use the private key. The first server receives, over the encrypted connection, a response to the request that includes a result of the use of the private key. The first server uses the result during the procedure to establish the secure session.

Abstract: An authoritative domain name system (DNS) server receives DNS requests for domains. The authoritative DNS server transmits DNS responses to the DNS requests with address records that include IP addresses that are selected from a larger pool of IP addresses, where a first DNS response can include IP addresses different from IP addresses included in a second DNS response for the same domain. Also, the same IP addresses may be returned for a first domain and a different, second domain. The authoritative DNS server may select the IP addresses to include in DNS responses to the DNS requests using a round-robin process.

Abstract: Systems and methods for demand-based marketplaces in accordance with embodiments of the invention are disclosed. In one embodiment of the invention, a demand-based marketplace server system includes a processor and a memory storing a demand-based marketplace application, wherein the demand-based marketplace application directs the processor to obtain product demand data, wherein the product demand data includes product keywords describing one or more products, identify product data corresponding to the product demand data, generate lead data based on the product demand data, wherein the lead data is targeted toward one or more seller systems associated with the identified product data, and transmit the lead data to the one or more seller systems.
