Preserved Topic: html meta tag question (Page 1 of 1)

what does

<meta http-equiv="pragma" content="no-cache">

???

thanks.

It instructs proxy servers not to cache page. There are also other directives like "Cache-Control" for example...

Doesn't it also tell the browser not to cache it? That's what I've always thought.

Actually, that depends from one browser to another. In my tests, almost all browsers ignored that completely...

BTW The best way to (try to) disable caching is to set HTTP headers directly:

<?
header ("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); // Date in the past
header ("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT"); // always modified
header ("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header ("Pragma: no-cache"); // HTTP/1.0
?>

thanks for the info, guys.

max, is there a possibility to set headers without a php or other script language?

You can use META tags, just like you did with the "pragma"...

oh yea, sure.
me idiot!
