Static, Client-Side and Server-Side Scripting Pages

This section describes differences of static content, client-side scripting code, and server-side scripting code.

If you are using IIS as the Web server and IE as the Web browser, you can 3 types of contents into a Web page:

Here, I have 3 Web pages to display a time in 3 different ways: static content, client-side scripting code, and server-side scripting.

1. time_static.html: A static page displaying a static time.

<html><body>The current static time is: 
11/26/1999 10:19:46 PM 
</body></html>

If you open this page with any Web browser, you should see the static time, which will not change when you open the page again some time later.

The current static time is: 11/26/1999 10:19:46 PM 

2. time_client.html: A client scripting page displaying the time dynamically out of the client system.

<html><body>The current client time is: 
<script language="vbscript">
document.write(Date & " " & Time)
</script>
</body></html>

If you open this page with any Web browser that can execute VBScript statements, like MS Internet Explorer (IE) 5, you will see the current time of the client system. The displayed time will change when you open the page again some time later.

The current client time is: 11/26/1999 10:26:08 PM 

3. time_server.asp: A server scripting (ASP) page displaying the time dynamically out of the server system. File name extension ".asp" is needed to inform Web server to be ready to execute the embedded script statements.

<%@ language="vbscript"%>
<html><body>The current server time is: 
<%
response.write(Date & " " & Time)
%>
</body></html>

Since an ASP page needs a Web server to execute the script statements, you need to copy this page to the document directory of the IIS server:

copy time_server.asp \inetpub\wwwroot

If you now open this page with IE 5 at http://localhost/time_server.asp, you will see the current of the server system. The displayed time will change when you open the page again some time later.

The current server time is: 11/26/1999 10:43:32 PM 

Notice that I am using the same scripting language, VBScript, for both time_clien.html and time_server.asp.
