Active Server Pages (ASP) is a tool that allows developers to create dynamic and interactive web pages. An ASP file contains HTML tags as well as server-side scripting that processes requests from the server and returns results to clients. ASP was introduced in 1996 and is bundled with Microsoft's Internet Information Server (IIS) web server. It allows developers to generate dynamic web pages, process form contents, and create database-driven websites.

6. Generates dynamic web pages
Processes the contents of HTML forms
Creates database driven web pages
Create searchable web pages & send E-MAIL
Components of Web site includes server side
components created with Visual Basic ,C++ or
Java.

7.  Commonly used for Interactivity.
Browser-dependent.
Viewable on client (Protecting source code).
Reduces the number of requests the server
receives.

8.  Greater flexibility .
Generate response for client.
Run exclusively on server .
Not visible to client.

9.  Client-side-script is embedded into the HTML file
using tags:
<script language =“Java script/ VB Script”>
{Java script/VBS code}
</script>
 Server-side-script is embedded into the ASP file
using tags:
<script language=VB script/java script RunAt
SERVER=server>
