[Phplib-users] controlled page expiry

[Frank B. <fb...@sy...>]

Background:

I recently wrote a script to convert my family research database to
postgresql; and then wrote a php page to dynamically present this data
instead of use the supplied tools which generate static html pages.  Since
the database contains private information about individuals, I have used
phplib sess/auth to control access to the dynamically generated pages.  The
conversion process will be run run at seemingly random times (sometimes
days, weeks or months apart) as my time and interest in this hobby varies.

Questions:

My database is only updated whenever I perform the conversion routine, so I
was thinking it would be nice to allow user to cache pages between
conversion runs.  I can place the last-changed information somewhere each
time the conversion script is run.  Once I do that, can I control
expiration of php page so that user can cache pages until next conversion
process is run?

Does anyone have some input as to how well this type of code might actually
work in real-life situations?
