SSL Accelerator?

Ordinarily the SSL handshake and subsequent encryption of data between a browser and the web server is handled by the web server itself. However for some extremely popular sites, the amount of traffic being served over SSL means that the web server either becomes overloaded or it simply cannot handle the required number of SSL connections. For such sites a SSL Accelerator can help improve the number of concurrent connections and speed of the SSL handshake. SSL Accelerators offer the same support for SSL as web servers.
