[PLUG] Paint an HTML in the "Background"?

I've got an application which regenerates and reloads a web page every 15 
seconds.  (The page is regenerated with a python cgi-bin script, and this 
process is triggered by the HTML directive "<META HTTP-EQUIV='REFRESH' 
CONTENT='15'>").   This system is simple and works very well.  I've got 
mostly text data, but there are 1 or 2 large graphics images in each page.

Unfortunately, the process of loading a new page clears out the old page, and 
is unsightly while the new one is being regenerated and downloaded.

I would like to be able to regenerate and download the new page while the old 
one is still being displayed, then instantly switch to the new page so as to 
minimize this 'redraw" phase.   

I'm not skilled enough to try to use some type of Java script, and the 
application isn't critical enough to motivate me to acquire the missing 

Does anybody know of a simple way I can freeze the existing page in a web 
browser until the replacement page is fully formed and rendered?
