           Summary: redirect to .swf file results in blank page or partial
                    load, direct link works.
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh
        OS/Version: Mac OS X 10.6
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Plug-ins
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: helio at geekshed.net


Test case page:

http://206.53.60.70/tflash.php

The current variation of this page:
<?php
        header("HTTP/1.1 301 Moved Permanently");
        header("Location: http://206.53.60.70/flash/TFlash.swf");
        exit();
?>

In the preceding variation, the swf loading bar does not complete, in a
slightly randomized way (it does work in some cases, but on browsers confirmed
working, it worked 100% of the time, rather then a small percentage of the
time).


A previous variation of this page:

<?php
        header('Content-type: application/x-shockwave-flash');
        header('Content-disposition: swf; filename="tflash.swf"; size=' .
filesize('flash/TFlash.swf'));
        header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
        header("Expires: Sat, 26 Jul 1997 05:00:00 GMT"); // Date in the past
        readfile('flash/TFlash.swf');
        exit();

?>

This only resulting in a blank page.

I apologize for the small sample set, and the inconsistencies of the versions.
These are from end users, so please apply fuzzing to 'working' and 'not
working'. Firefox, Opera, Internet Explorer, and Google Chrome in various forms
and permutations do not seem to show the bug. It seems to be limited to updated
Safari versions on OS X 10.6.2. I apologize if this bug is not strictly a
WebKit bug, my sample size doesn't give me the confidence to rule it out.
