Controlling Response Header Line Example

This section provides tutorial example on 2 ways to control HTTP response header line in an ASP script page: Using response.ContentType and response.Charset properties; and using response.AddHeader() method.

Now, I know that my HttpRequestGet.java works correctly. Let me use it to view ASP tutorial examples to show you 2 ways to control HTTP response header lines described in a previous section.

The first example, set_content_type.asp, uses the special properties of the response object:

<script language="vbscript" runat="server">
'  set_content_type.asp
'  Copyright (c) 2002 by Dr. Herong Yang
   response.ContentType = "text/plain"
   response.Charset = "ISO-8859-1"
   response.Write("<html><body>Hello world!</body></html>")
   response.End()
</script>

The response:

HTTP/1.1 200 OK
Server: Microsoft-IIS/5.0
Date: Sat, 28 Dec 2002 23:05:34 GMT
Connection: Keep-Alive
Content-Length: 38
Content-Type: text/plain; Charset=ISO-8859-1
Set-Cookie: ASPSESSIONIDQGQQGVCU=PMOHPEODJIKOLILLKJICNNPI; path=/
Cache-control: private

<html><body>Hello world!</body></html>

Note that the Charset property is used as a parameter in Content-Type header line.

In the second example, add_header.asp, I am trying to use the generic methods to add various header lines:

<script language="vbscript" runat="server">
'  add_header.asp
'  Copyright (c) 2002 by Dr. Herong Yang
   response.AddHeader "Content-Type", "text/xml;charset=UTF-8"
   response.AddHeader "Author", "Herong Yang"
   response.AddHeader "Author", "Joe Wang"
   response.Write "<html><body>Hello world!</body></html>"
   response.End
</script>

Here is the response:

HTTP/1.1 200 OK
Server: Microsoft-IIS/5.0
Date: Sat, 28 Dec 2002 13:46:53 GMT
Content-Type: text/xml;charset=UTF-8
Author: Herong Yang
Author: Joe Wang
Connection: Keep-Alive
Content-Length: 38
Content-Type: text/html
Set-Cookie: ASPSESSIONIDQGQGGOSU=IEBDDENBHEFCBLJJKDKAKICH; path=/
Cache-control: private

<html><body>Hello world!</body></html>
