The following META tag should do the trick. Just insert it into your HTML file, at the < head > part of it.

Netapps caches ignore such meta tags, not sure about Inktomi and Squid, but I'd imagine they are the same...

yep, won't do anything if your ISP or reader's ISP caches... i learnt that the hard way!

if ur using apache - then u can use mod headers/expires to control what gets cached etc

if ur using PHP, then it's also possible by adding something like

Code:

$now = gmdate("D, d M Y H:i:s") . " GMT";
header ("Date: $now");
header ("Expires: $now");
header ("Last-Modified: $now");
header ("Pragma: no-cache");
header ("Cache-Control: no-store, no-cache, max-age=0, must-revalidate");

ooops, sorry Justin Tan, i didn't notice that u were on Tripod. One 'cheat' way to get your page not cached is to use that TRIPOD 'cache buster' code that they use to serve their banner ads, on your pages!

Most caches wont cache your site if its mainly cgi as cgi is mostly dynamic content.

Add just bellow the title tag:

Code:

This way the page will be already expired so it won't be cached.

That meta tag is ignored by a vast quantity of browsers out there. The header is usually a more reliable way of preventing caching, but even then some things ignore it.

The best way is to change all the extensions of your .html files to .php, if you use no PHP at all, and if you do, with .htaccess help, you could have a .phtml extension that is not parsed. Then the cacheing program will think it's dynamically generated, when in actual fact it's not.
