The user enters a website that connects to a server which is secured with SSL. On that situation, you can see that the address of the website starts with https://, try to start with HTTP://. The Browser can also demands the identification of data from the server. Then the servers agree the request that is sending a copy of its SSL Certificate and browser proves the certificate. But if the certificate is valid then the browser sends back a symmetric session key.
Server sends back the responsein appropriate manner to start the secure session with the browser with the key he got. The communicatebetween both server and browser are now together in a secure environment.
