ASP Introduction and IIS installation methods in Windows


What you should already know
Before you continue you should have some basic understanding of the following:
  • HTML / XHTML
  • A scripting language like JavaScript or VBScript
If you want to study these subjects first, find the tutorials on our Home page.


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
ASP Compatibility
  • To run IIS you must have Windows NT 4.0 or later
  • To run PWS you must have Windows 95 or later
  • ChiliASP is a technology that runs ASP without Windows OS
  • InstantASP is another technology that runs ASP without Windows
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
NoteNote: Because ASP scripts are executed on the server, the browser that displays the ASP file does not need to support scripting at all!

Run ASP on Your Own PC


You can 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


IIS - Internet Information Server
IIS is a set of Internet-based services for servers created by Microsoft for use with Microsoft Windows.
IIS comes with Windows 2000, XP, Vista, and Windows 7. It is also available for Windows NT.
IIS is easy to install and ideal for developing and testing web applications.


PWS - Personal Web Server
PWS is for older Windows system like Windows 95, 98, and NT.
PWS is easy to install and can be used for developing and testing web applications including ASP.
We don't recommend running PWS for anything else than training. It is outdated and has security issues.


Windows Web Server Versions

  • Windows Vista Business, Enterprise and Ultimate come with IIS 7
  • Windows Vista Home Premium comes with IIS 7
  • Windows Vista Home Edition does not support PWS or IIS

Test Your Web
After you have installed IIS or PWS follow these steps:
  1. Look for a new folder called Inetpub on your hard drive
  2. Open the Inetpub folder, and find a folder named wwwroot
  3. Create a new folder, like "MyWeb", under wwwroot
  4. Write some ASP code and save the file as "test1.asp" in the new folder
  5. Make sure your Web server is running (see below)
  6. Open your browser and type "http://localhost/MyWeb/test1.asp", to view your first web page
Note: Look for the IIS (or PWS) symbol in your start menu or task bar. The program has functions for starting and stopping the web server, disable and enable ASP, and much more.


How to install PWS on Windows 95, 98, and Windows NT
For Windows 98: Open the Add-ons folder on your Windows CD, find the PWS folder and run setup.exe to install PWS.
