Safari and Redirect Error

Question

I have a web app that uses a 302 redirect to download a file off of Amazon S3. The download works fine in IE6, IE7, Firefox on Mac and PC, and Opera for Mac. But it fails in Safari with a signature error from Amazon.
If I print the URL as produced by my app and paste it into Safari it works, but if I try to redirect to it, it does not work. Here is my redirect:
$r->method('GET');
$r->headers_in->unset('Content-length');
$r->content_type('application/octet-stream');
$r->headers_out->{'Location'} = $url;
$m->abort(302);
I'm using Apache 1.3.37 and mod_perl 1.30.
When I ran this process through Wireshark, I discovered two very strange things: Safari's destination IP address for the GET request is different from that of other browsers. In fact, it does not resolve to anything at all, whereas the other browsers have a destination IP address that does resolve to Amazon, if I use a reverse DNS lookup tool.
Also, Safari seems to be ignoring my content-type header, and it makes its own: Content type application/x-www-form-urlencoded. This is incorrect for GET requests, I think.
Safari is the only browser that causes this problem. Does anyone have any idea how to fix this?

Also, this only happens in Safari 3 on Leopard. Not on Tiger.
