Each time the page is accessed, it displays different content. You may find the home page changes according to the time of day or the type of interaction you make. Websites that are dynamic have two types.
SCRIPTING FOR CLIENTS
The use of client-side scripts is necessary for changing the behavior of web pages in response to events contained on those pages.
SCRIPTING ON THE SERVER
If a page changes when a user visits or loads it, server-side scripting is used. A server-side script creates content when a web page is loaded. The login pages, forums, submission forms, and shopping carts are all scripted pages since they are dynamic in response to user input. Scripting languages like PHP, ASP, ASP.NET, JSP, ColdFusion, and Perl are used to handle submissions on the web.
