felgall, thank you for the reply.
Your second paragraph addresses programming techniques that I am unfamiliar with.
I gather, therefore, that there is no way to alter the loading pattern of the current page.
I'm game to consider a different plan, but radically new may be more than I can absorb today. If you can direct me to some examples or tutorials of the concepts involved, or provide some example code I would be grateful. My goal is to have this ready for the website by the first of next year, so there is time to learn a new trick or two <smile>.
