Patent 7870380 was granted and assigned to Aventail on January, 2011 by the United States Patent and Trademark Office.
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.
