The Caching Proxy supports Secure Sockets Layer (SSL) connections. SSL is a security protocol that uses encryption and authentication techniques to ensure secure communication between a client and a server.
SSL uses a security handshake to protect the TCP/IP connection between the client and the server. During the handshake, the client and server agree on the security keys they will use for the session, and the client authenticates the server. After that, SSL is used to encrypt and decrypt all of the information in both the HTTPS request and the server response.
To use SSL, you must configure some basic information first. The Caching Proxy Administration Guide provides more detailed information about configuring and using Secure Sockets Layer (SSL) in the Caching Proxy for secure remote administration.
After you have enabled SSL, you might want to make some performance changes. You can modify the amount of time, in seconds, that an SSL session lasts before it expires. After the SSL session expires, the encryption key for the session will be regenerated if further communication is required. Key generation is resource-intensive.
