Thanks for the ideas, but my scripts will be accessed very infrequently and 
I will not remember to convert them to static pages each time I make 
changes to them.  I have figured out that inserting the following line at 
top of a script appears to cause browser to cache the page (at least for 
current browser session, close/reopen browser and pages are retrieved again 
- as expected).

header('Last-Modified: '.date( 'r', 
filemtime($HTTP_SERVER_VARS['SCRIPT_FILENAME']) ));

But scripts that call phplib's page_open function are not affected (ie: not 
cached) by this change?
