What is a secure server?
A secure Server guarantees the privacy of your personal details transmitted through the net. This privacy is reached via the encrypted protocol SSL 128 bits. The safety is the result of the communication between a low protocol SSL navigator and a server with the same protocol. Any version of the browser Netscape Navigator and Microsoft Explorer handle this protocol.
How can I know this is a secure server?
By the key you will find at the bottom left part of Netscape, or by the lock you will find at the bottom right part of your navigator if you are using Microsoft Explorer. You could also see that the URL varies. It does not start by http but by https.
