The Buffer property indicates whether to buffer page output. When page output is buffered, the server does not send a response to the client until all of the server scripts on the current page have been processed, or until the Flush or End method is called.
If the current .asp file has Buffer set to TRUE and does not call the Response.Flush method, the server honors keep-alive requests made by the client. This saves time because the server does not have to create a new connection for each client request.
However, buffering prevents any of the response from being displayed to the client until the server has finished all script processing for the current page. For long scripts, this may cause a perceptible delay.
Client: Requires Windows XP Professional, Windows 2000 Professional, or Windows NT Workstation 4.0.
