Buffered Output in ASP

In the previous example all the web pages content was sent to the browser immediately. Buffering can be used to store information for a period of time or upon response to an event before releasing the data. Note that

Response.Buffer = TRUE buffers the page output and sends the client browser a response when the Flush or End methods are called.
Response.Clear clears the output buffer.
Response.Flush sends the output buffer to the cliemt immediately.
Response.End sends all buffer content to the client and stops web page processing; if the Response.Buffer attribute is set to TRUE.

<% @LANGUAGE = VBScript %>
<% Option Explicit %>

<%
Response.Buffer = TRUE
Response.Expires = 60
%>
<HTML>
<BODY>
Hello User.<BR>
You are seeing the present hours' message.
<%
Response.Clear
Response.Expires = 0
%>
<HTML>
<BODY>
This is the fast expiring message.
<%
Response.Flush
%>
</BODY>
</HTML>
<%
Response.End
%>
This line will never be sent to the browser.
