Abstract
The disclosure provides a method and apparatus for transmitting data securely using an unreliable communication protocol, such as User Datagram Protocol. In one variation, the disclosure describes retaining compatibility with conventional Secure Sockets Layer (SSL) and SOCKS protocols, such that secure UDP datagrams can be transmitted between a proxy server and a client computer in a manner analogous to conventional SOCKS processing. Further, the disclosure describes a network arrangement that employs a cache having copies distributed among a plurality of different locations. SSL/TLS session information for a session with each of the proxy servers is stored in the cache so that it is accessible to at least one other proxy server. Using this arrangement, cached SSL/TLS communication session information may be retrieved and used by a second proxy server to accept a session with the client device when the client device switches proxy servers.
