What is SSL?
SSL stands for Secure Socket Layer (SSL). Originally developed by Netscape and now a de-facto standard for secure communication over the internet, SSL is implemented by all secure web servers and browsers like Internet Explorer, Firefox, Safari, Opera etc.
Where SSL is used
The widest use of the SSL protocol is done in browsers. It will secure the browser of any site on the internet, for example: for login pages, or online banking, or any other financial site. Accessing any site starting with https:// in the address bar of the browser initiates the SSL connection between the browser and the SSL server, e.g. https://www.paypal.com in your address bar will establish a secure SSL connection between the browser and the web server of www.paypal.com. Apart from this SSL can be used in FTP or any other application layer protocols. SFTP implements SSL for FTP.

It allows you to dynamically change a part of the page, or the whole page, without any visible refresh or flicker. The data transfer is so seamless and smooth that in some cases, you may not notice the change. Ajax » » »
