If the page is found and it has not expired, Net. Data stops processing the macro, exits from the macro, and sends the cached page to the Web browser. If the requested page is not in the cache or the existing cached page is older than the value of age , Net. Data generates a new output page. When the macro successfully completes, Net.
Data sends the new page to the browser and caches the page.
This technique makes it easier to maintain the macro when the macro is updated. For example, when the function is in the middle of the macro, it might not be noticed when a HTML report section is added earlier in the macro. Data would not cache the new report output. Additionally, this method improves performance as Net. Data stops all further processing when it determines that the page is cached.
