Bug 33463 – redirect to .swf file results in blank page or partial load, direct link works.

• Status: RESOLVED
• Resolution: WONTFIX
• Component: Plug-ins

[Dylan Cochran]

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.

Mass closing plug-in bugs, as plug-in support has been removed from WebKit.

Please comment and/or reopen if this still affects WebKit in some way.
