#2038 — A question about refresh

I have a page that gathers information from a database and shows a 
status.  Asynchronously, some other process modifies that status at a 
shortly later time.

I have placed a button on the page to do a refresh of the page. I use 
location.reload() as the onClick method.

Here are the results:
1 - Clicking the button does not show the changed status
2 - Hitting F5 does not show the changed status
3 - Clicking the refresh button on the menu bar does not show the 
changed status
4 - Clicking the arrow to the right of the address field DOES show the 
changed status.

I would like to know how I need to code my refresh button on the page so 
that it shows the changed status like #4 above.  Any help will be 
appreciated.

(I have looked quite a bit through Google, but haven't found the answer 
and changing an ini file is not really an option as this is a 
mult-purpose page -- I inherited this rather old code).

It would better be changed soon, before it is too late.

Not my call!  Besides, this is an INTRAnet application, so all users are 
known.  There is no way they are going to revamp everything in this 
massive application.  It still uses the feature that there are variables 
that are the same name as the fields automatically without using gets or 
posts.

What kind of developer are you anyway?  No, don't answer.

Irrelevant.

All users are … listen to yourself!

Then they deserve what they will get.

  foreach(array('x', 'y', 'z') as $var)
  {
    $$var = $_REQUEST[$var];
  }

does the same without compromising all security, preferably in local context 
(you might want to exclude $_COOKIE, though).

So are you capturing the returned response from the ajax call?
Are you 100% sure that the information is being written to the
database?

If it were not for 2, 3, and 4, window.location.replace(document.URL, true)¹ 
would have sufficed.  However, because of those, you need to apply 
<http://www.mnot.net/cache_docs/>.

This problem cannot be solved with client-side scripting alone.

It looks like your browser is caching results, something like this:
<?php
header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header("Expires: Sat, 26 Jul 1997 05:00:00 GMT"); // Date in the past
?>
(from: http://php.net/manual/en/function.header.php) might work. Your
browser should stop caching the results.
