One more question - php & mysql

If I load my page up, then add some more details in my database, when I revisit the page it still shows the old data unless I force a refresh.

How do I get it to reload the page always - is there a meta tag I should use?

Thanks............again

It is most likely going to be just your internet explorer storing a copy of your page. Go to tools -> internet options -> Settings -> and change the option.

PHP pages arn't normally cached by other servers, (unless you work hard to do it) so this isn't nomally a problem unless you expect to update the data in real time (e.g. a shoping cart page).

you can do it by adding the following lines to the VERY START of your php files, but these will cause the browser to re-request the page at every view - i.e. even if they are just clicking the back button to get to the page.

<?
header("Cache-control: no-cache");
header("Expires: " . gmdate("D, d M Y H:i:s") . " GMT");
?>

(you may need to replace <? ?> with what ever php start and end flags you are using)

Again, I'd only do this in certain situations as it will cause more request to the site, therefore a slower browsing experience.

In later versions of IE, caching could also be because your clock is set wrong on your PC (no, I'm not joking). If it's not set right, it could override any IE settings you have and refuse to fetch the new page.
