About web applications
A web application is a website that contains pages with partly or entirely
undetermined content. The final content of a page is determined only
when the visitor requests a page from the web server. Because the final
content of the page varies from request to request based on the visitor’s
actions, this kind of page is called a dynamic page.
Web applications are built to address a variety of challenges and problems.
This section describes common uses for web applications and gives a
simple example.
