Generating static pages on the server - caching problem

I am generating static HTML pages from a PHP script that forms the content based on a database query. One problem is that old page gets cached. For instance, if I write, http://localhost/index.php, from a PHP script called http://localhost/generateindex.php, when I call the URL http://localhost, I get the old content. When I call the URL explicitly http://localhost/index.php, I get the updated information. I think this has something to do with the way that Apache is serving up the cached pages but not sure where to start looking. Is there a module directive that I should look into. I have not tried this on my production server which is running FreeBSD with Apache. I am seeing this on my testing site which is running Apache on top of Win XP Pro. Any ideas?
