Foil 27 Dynamic Web Pages --- Client Pull

From CGI Programming with Advanced Topics Jackson State University Mississippi -- Fall Semester 97. by Nancy McCracken *

The web server can send an HTTP response with a header of type Refresh. This causes the browser to request a new page automatically after some time.
In Server Push, the HTTP connection is kept open between the browser and the server for the duration of the responses. In Client Pull, the connection is closed and reopened each time the browser sends another request for a refresh. Thus Server Push is best for small size files that are going to be sent at small intervals, like animations of small images, and Client Pull is best for larger or longer interval transmissions, such as stock ticker updates.
