Terminology• IIS
– Internet Information Server
• ASP– Active Server Pages
Microsoft’s Definition
Active Server Pages is an open, compile-free application environment in which you can combine HTML, scripts, and reusable ActiveX server components to create dynamic and powerful Web-based business solutions. Active Server Pages enables server-side scripting for IIS with native support for both VBScript and Jscript.
Static Content .vs. Dynamic Content
• Static Content– Does NOT change from unless author
updates the file
• Dynamic Content– Is generated “on the fly” when the
page is called into existence
Advantages of Dynamic Content
• Can more easily be kept current• Can adapt to user preferences• Can be maintained more easily• Information can be presented in
more than one form
Disadvantages of Dynamic Content
• More complex• Not easily searched• Slower
A different System for every purpose
• Application Development System• Content Management System• Information Management System• Web Development System• Document Management System
What do they have in common?
• Information– Acquisition– Storage– Management– Presentation– Organization
Important Functions/Subsystems
• Simple• Powerful• Web-based
– All Functions (Acquisition, Management, Storage, etc)
• Dynamic Generation of Content
Important Functions/Subsystems
• Database Back End– Single copy of Information – Content/Format separate
• Production and Development Environments– Separate Completely– Easy Migration – Both Environment fully functional
Competing Systems• Php • Perl• Cold Fusion• Dreamweaver• Front Page
Why IIS and ASP?
Fairly Popular Web Server (30%)
Fairly Cost Effective• $81
– Windows Server 2003 – Standard Edition– Texas State Contract– Educational Pricing– Enterprise Edition $323.90
Support• Available (but expensive)• User Groups• News Groups• Web Site (MSDN)• Internet Resources
Active Server Pages• Easy to write• Easy to read• Easy to debug• Easy to acquire
– Web resources– Experts are out there
Scripting Languages• Visual Basic Script • Java Script• C#
Servers for ASP?• Windows Server 2003• Windows 2000 (Server or Client)• Windows XP • Windows NT (Server or Workstation)• Windows 9x• Apache (with Apache::ASP extension)• Solaris (with Sun One ASP)
How do I use ASP?• Create a HTML-like file and save it with
a .asp suffix (file type)• Upload to a server• Browse the file• Did it Work?
– Yes, Great– No, note the error, fix, re-upload, try again
What does ASP Look Like?
• Start file with language definition– <%@ LANGUAGE = VBScript %>
• Code HTML Normally– <HTML>
• <HEAD>– <TITLE>This is my first ASP File</Title>
• </HEAD>
What Does ASP Look Like?
• Want to execute some code– <% (to start code segment)
• Response.Write “Hello World”
– %> (to return to HTML segment)
• Want value of variable in HTML segment?– <%= myvariable %>
A Simple ASP ExampleExample 1
• <%@ LANGUAGE = VBScript %>• <%• For I = 1 to 100• Response.Write “Hello World<BR>”• Next• %>
Another Simple Example
Example 2• <%@ LANGUAGE = VBScript %>• <TABLE BORDER=10><%• For I = 1 to 10• %><TR><%• For J = 1 to 5• %><TD BGCOLOR=RED><FONT
COLOR=YELLOW>Hello World</FONT></TD><%• Next• %></TR><%• Next• %></TABLE><%%>
Another Simple Example
Example 3• <%@ LANGUAGE = VBScript %>• <%• Response.Write "<TABLE BORDER=10>"• For I = 1 to 10• Response.Write "<TR>"• For J = 1 to 5• Response.Write "<TD BGCOLOR=RED><FONT
COLOR=YELLOW>Hello World</FONT></TD>"• Next• Response.Write "</TR>"• Next• Response.Write "</TABLE>"• %>
More Examples
Conclusion• IIS and Active Server Pages
– Easy to code– Inexpensive– Available– Powerful– Dynamic
