  • Patent number: 6185608
    Abstract: Web pages for commercial applications, such as electronic retail, are built “on-the-fly” in Hypertext Markup Language (HTML) from product data stored in the merchant's database. To reduce costs in time and computing resources and to improve customer access to data from the merchant's web site, pages created in HTML are cached on the merchant server. On a customer request for a page, the merchant server checks the cache first for the page, and if it isn't found there, generates a new page from the database. To maintain the validity of the content of the cached pages, the database tables include triggers that cause identifying information for any changes made on the stored data to be forwarded to a cache log. A synchronization daemon walks the cache log from time to time to locate pages that should be purged from the cache because their content is no longer synchronous with the data stored in the database.
