forced refresh 1

[newbiepg]

how can i ensure that when a user visits a page using the
browser back button he gets a dialog asking him to refresh the page?

I am looking something like using Cache control

Thanks

There are no cache-conrol HTTP directives that I know of that will cause a dialog to pop up. There may be a way of doing it using client-side scripting. If so, you should ask the question in one of the client-side scripting fora.

You could use a PHP variable and a meta refresh... in the head do a check like:

<?php //parse url
  if($page_name != &quot;this page&quot;)
     print(&quot;<META HTTP-EQUIV=Refresh CONTENT='0; URL=http://www.somesite.com/thispage.html?page_name=thispage'>&quot;);
?>

The code above is incomplete, just trying to give you some ideas...

That will perform a refresh on the current page. I don't believe it will cause a refresh if it's cached and you go back to it in the history list. And even if it does, it's not going to pop up a dialog box.

that is what I should have done
i can do a check whether the last page was
the current page using javascript and if not force a refresh.

thanks
