i bet my life this has been asked a hundred times, so my apologies.
how can i make the web browser, check if a html page has been modified and make sure
the user is viewing the latest version.
i' am not refering to a simple meta-refresh or expires,, is there a way to make the browser
check and compare the last modified time of the html file say every 60 seconds,, but not
refresh the display ( as this produces flicker ) if the html file is unchanged..
