           Summary: reload of page with an iframe does not refresh iframe
                    content, even if iframe src url changed
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Windows XP
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Frames
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: antony at asargent.com

Navigate to an html page with some content followed by an iframe tag. Now make
a change to the contents and make the iframe src attribute point to a different
url. Hit browser reload button, notice that the "outer" content is refreshed
but the iframe content still points to the content at the old url. This problem
happens with Safari 3.1.2 (525.21), the latest WebKit nightly build (36446),
and Chrome 0.2.149.30. It does not happen in Firefox 3.0.1 or IE 7.0.7530.13.

Here is the source to two example php files to reproduce the problem:

iframe.php
----------
<?php
$ts = date('U');
?>
<html>
<body>
<p>
Timestamp is <?= $ts ?>
</p>
<iframe src="report_url.php?foo=<?= $ts ?>"
        width="75%" frameborder="1"></iframe>
</body>
</html>

report_url.php
--------------
<html>
<body>
<?php echo $_SERVER['REQUEST_URI'] . "\n"; ?>
</body>
</html>

While this example just changes the value of the foo get parameter, the problem
also happens if you change the iframe src url to another path on the same
server or another server alltogether.
