How to force no-cache

[Manaus]

Hello,

I have a page making ajax calls, but when I go back and forth with the browser I see just the cache content. Is there any way to prevent this?

I tried with all the meta tags available on the market today...

Perhaps it will help to add these headers (just after the opening <?php call) to the top of your template file that is delivering the data to ajax

if($config->ajax) {
    header("Cache-Control: no-store, no-cache, must-revalidate, max-age=0");
    header("Cache-Control: post-check=0, pre-check=0", false);
    header("Pragma: no-cache");
}

Thanks Raymond (nice picture!),

I think the cached page is the caller, not the ajax stream...
