Before you continue you should have a basic understanding of the following:

(i) WWW, HTML and the basics of building Web pages
(ii) Scripting languages like JavaScript or VBScript
(iii) The basics of server side scripting

What is ASP?

ASP is a server side scripting technology that enables scripts (embedded in web pages) to be executed by an Internet server.

· ASP is a Microsoft Technology

What is an ASP File?

· An ASP file is just the same as an HTML file
· An ASP file can contain text, HTML, XML and scripts
· Scripts in an ASP file are executed on the server
· An ASP file has the file extension ".asp"

How Does it Work?

· When a browser requests an HTML file, the server returns the file
· When a browser requests an ASP file, IIS passes the request to ASP
· ASP engine reads the file, line by line, and executes the scripts in the file
· Finally, the ASP file is returned to the browser as plain HTML
