Introduction to ASP
An ASP file can contain text, HTML tags and
scripts. Scripts in an ASP file are executed on the server
What you should already know
Before you continue you should
have some basic understanding of the following:
- WWW, HTML and the basics of
building Web pages
- A scripting language like
JavaScript or VBScript
What is ASP?
- ASP stands for Active
Server Pages
- 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
- ASP is a Microsoft Technology
- 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
- Provides security since your
ASP code can not be viewed from the browser
- Since ASP files are returned
as plain HTML, they can be viewed in any browser
- Clever ASP programming can
minimize the network traffic
