Enable Last Modified Header

What's this option? can you explain on this a little?

Thanks.

It's mostly for ie users. In generally, you can leave it as default unless you have cache issues.

can anybody give more details or example about this new feature Enable Last Modified Header


still dont understand so i dont know want to use it or not


more information please guys if you know

a header is part of the http protocol.

header has a ton of options: PHP: header - Manual

this one refers to adding a
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
style header to the code, so that a browser ALWAYS thinks it's been modified since it last loaded the page, thus not using the browsers own cache.

it's slower for the user
it's costs bandwidth for you

There's no good reason to use it unless you have caching issues (changed styles, etc)

hmm thanks for the more details

dont know am i have caching issues or not for now, will learn it again

You most likely are not. 99.9% of the time, you can leave this disabled. It's more designed for IIS/ie than anything.
