This technical note presents a way to prevent users from seeing cached versions of web pages when accessing a 4D V6 database from a web browser.

ACI Pack’s AP SET WEB FILTERS command allows you to filter the outgoing HTML from 4D, in this case to insert an EXPIRES meta-tag into the header of the outgoing stream. The result is that a user attempting to access an out-of-date page from 4D should not see the original page, assuming the browser they are using supports this tag.
