Smarty with Page Expires

[rejoice]

Does anyone know how to generate a page with smarty and the page has an expiry date?

How can we check whether this function has taken effect?

source:
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"

Many thanks.

Can we put something in HTML page to expire the page? If yes, how would the code look like?

It is the browsers that process the cache directives. And, of course, every browser does it differently. You can look into the 'pragma no-cache' and other meta tags in the page, but be aware, that browsers act differently.
For example, even though you might put the most restrictive cache headers and page expiration into the HTML, even a 'must revalidate', browsers such as Opera will not reload the page when the back button is used. Their developers have the standpoint that the RFC requires a reload only when the page is accessed through a link.
Do a quick google for meta tags for cache control.

oic.

By the way, why should we use META tag? instead of Javascript? Can Javascript force the page refresh?

 

[DRJ478]

Javascript turned off -> no reaction to anything you code.
META tags are standard tags that are introduce "header" fashion information and cannot be "turned off".

Actually, that's not necessarily true. Opera, for example, gives the user the option of turning off processing of the "Refresh" meta-tag.
