The disclosed system and method allow secure packet transmission to be provided with a minimum amount of overhead and to employ 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, when a client computer switches from a connection with a first proxy server to a connection with a second proxy server, the second proxy server can retrieve SSL/TLS session information from the cache corresponding to the SSL/TLS communication session between the client device and the first proxy server. The second proxy server can then use the retrieved SSL/TLS session information to accept a session with the client device.
