What is ASP?
ASP stands for Active Server Pages
ASP is a Microsoft Technology
ASP is a program that runs inside IIS
IIS stands for Internet Information Services
IIS comes as a free component with Windows 2000
IIS is also a part of the Windows NT 4.0 Option Pack
The Option Pack can be downloaded from Microsoft
PWS is a smaller - but fully functional - version of IIS
PWS can be found on your Windows 95/98 CD
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 ASP Differ from HTML?
When a browser requests an HTML file, the server returns the file
When a browser requests an ASP file, IIS passes the request to the ASP engine. The ASP engine reads the ASP file, line by line, and executes the scripts in the file. Finally, the ASP file is returned to the browser as plain HTML
What can ASP do for you?
Dynamically edit, change, or add any content of a Web page
Respond to user queries or data submitted from HTML forms
Access any data or databases and return the results to a browser
Customize a Web page to make it more useful for individual users
The advantages of using ASP instead of CGI and Perl, are those of simplicity and speed
Provide security - since ASP code cannot be viewed from the browser
Clever ASP programming can minimize the network traffic
Run ASP on Your Own PC
Your Windows PC as a Web Server
Your own PC can act as a web server if you install IIS or PWS
IIS or PWS turns your computer into a web server
Microsoft IIS and PWS are free web server components
