How Does Oracle9iAS Portal Work? back | 1 2 3 4 5 6 7 8 9 | next
When a browser requests an Oracle9iAS Portal page: Oracle9iAS Web Cache fulfills the request if it contains a valid cache of the page. Otherwise, the request is forwarded to the HTTP server, which routes it through mod_plsql to an Oracle9iAS repository, which contains the required metadata. The database server processes the requests according to customization rules and sends it to the multithreaded servlet, which initiates portlet requests to providers. Valid cached portlets are returned from the Oracle9iAS Portal Cache. Providers return other portlets to the engine. The engine aggregates the content into a single page, which is then returned to the browser.
