------- Comment #1 from ap at webkit.org  2008-03-18 01:25 PDT -------
I suspect that this may be caused by a broken (empty) Cache-Control header in
the server response:

HTTP/1.1 200 OK
Date: Tue, 18 Mar 2008 08:07:54 GMT
Server: Apache/2.2.3 (Linux/SUSE)
Last-Modified: Thu, 04 Oct 2007 22:27:30 GMT
ETag: "18414b-51031-43bb24aae5880"
Accept-Ranges: bytes
Cache-Control: 
Expires: Tue, 18 Mar 2008 08:07:54 GMT
Vary: Accept-Encoding
Content-Encoding: gzip
Pragma: 
Keep-Alive: timeout=15, max=100
Connection: Keep-Alive
Transfer-Encoding: chunked
Content-Type: application/x-shockwave-flash

Some experimentation would be needed to determine if this is indeed the cause.

> Also, IE and Firefox/Mozilla seem to handle these particular SWFs just fine.

Even though the response is malformed, this difference in behavior can be seen
as a bug in system frameworks below WebKit, and thus needs to be filed at
<http://bugreport.apple.com> for Apple engineers working on those to take a
look.
