Net.Data can cache dynamic Web pages, thereby improving performance by eliminating the cost of reconstructing repeatedly requested Web pages. Web page caching is available when using ICAPI, GWAPI, or Net.Data Servlets.
Net.Data caches ACSII encoded Web pages in DB2. Using caching directives, you can specify which Web pages are cached, how long they remain valid in the cache, and the degree to which the reuse of the cached pages is restricted. Net.Data provides automatic management of the cache based on expiration time, and a macro that allows a system administrator to manage the cache based on macro and HTML block names and on the creation time for the cached page.
A cached page is static. Its content depends on the state of the data stores and business logic at the time the Web page was created. Subsequent changes to the data stores and business logic do not affect the content of the cached page.
