为什么Perl的CGI :: cookie能够在IE中设置cookie,而不是Firefox

我有一些Perl CGI代码,我试图在SourceForge帐户的项目Web空间中运行.在与IE交谈时,代码能够很好地设置浏览器cookie,但在与Firefox交谈时没有设置cookie.当我在“localhost”上使用Apache进行测试时,两个浏览器都能正常工作.它只在Firefox疯狂的远程SourceForge URL上.

搜索已经发现了几十个近似重复的问题,但通常人们会遇到完全相反的问题！ (Firefox很好,IE有问题)

这是我要求设置cookie的实用程序子：

sub setCookie {
    my $name = shift;
    my $value = shift;
    my $expires = shift;
    my $path = shift;
    my $domain = shift;
    if( !defined( $expires ) ) {
        $expires = '+4h';
    }
    if( !defined( $path ) ) {
        $path = '/';
    }
    if( !defined( $domain ) ) {
        $domain = 'steveperkins.sourceforge.net';
    }
    my $cookie = CGI::cookie(
        -name    => $name,-value   => $value,-domain   => $domain,-expies => $expires,-path    => $path
    );
    $r->header_out('Set-cookie' => $cookie);
}

有任何想法吗？我的第一个想法是某种子域问题,因为我的SourceForge项目URL中有一个子域,而“localhost”没有.我已经尝试将cookie域设置为我的特定子域,或者只是基础“sourceforge.net”.它似乎没有任何区别.

更新：以下评论中的某人询问了HTTP响应标头.我使用网络流量分析工具Wireshark来监控IE和Firefox的请求和响应标头,这是它们的样子：
