Supporting virtual servers with Server Name Indication
Server Name Indication lets you operate more than one SSL-protected service per IP address.
Web users and developers are equally devoted to the goal of keeping attackers from sniffing online orders, logging credit card numbers, and plundering user accounts. Fortunately, the introduction of Secure Socket Layer, a protocol for encrypted data transmission and reliable identification, helps prevent this horror scenario by offering a means for protecting sensitive web activities such as online banking.
The https protocol integrates SSL with http for secure web communication. With the use of encryption parameters that are negotiated with the use of the DNS name of the server, https establishes a secure connection.
