Outdated: Visiting "https" Web Site with IE 7
This section describes how IE (Internet Explorer) 7 shows a lock icon when you visit an 'https' Web site to provide you more security related information.
As I mentioned in the previous section, if a Web site wants to encrypt communication messages with your browser, it will enable the SSL protocol and use "https" as part of their Web address.
If you go to a Web site that provides online services, I am sure that you will see "https" in the Web address field starting on the log in page. This indicates that Web site uses SSL protocol to encrypt all information you send and receive on this server.
If you are using IE (Internet Explorer) 7, it will display an extra lock icon next to the Web address field when you are connecting to an "https" Web site. The picture below shows the "https" Web address and the lock icon when you use IE 7 to visit the Yahoo log in page: "https://login.yahoo.com":
If you click the lock icon, IE will provide you more information on security related to this Web site.
