Abstract

A website snapshot is the state of a web site at a specific point in time. It supports applications that require historical data. Most website snapshots are created by making a copy of the website. These date-time stamped physical snapshots are unable to satisfy users’ need for snapshots of different snapshot times. This research proposes a scheme that is able to create website snapshots that meet any snapshot time requirements by recording changes to a website in a log. For web pages producing dynamic content from a database, this scheme will allow the pages to access a database snapshot at the website snapshot time.
