I have had the same problem, and apparently this problem occurs on certain releases of 
Microsoft Internet 
Explorer only. I have never seen Netscape behave this way. Can you confirm this ?

What I did to correct this, is change the httpd.conf manually to disable HTTP/1.1 on 
Explorer SSL 
connections and a few other things.

Look for a section that has a lot $PerlConfig .= lines in it.

Then add this to both sections:

 $PerlConfig .= "SetEnvIf User-Agent \".*MSIE.*\" \\n";
 $PerlConfig .= "        nokeepalive ssl-unclean-shutdown\\n";
 $PerlConfig .= "        downgrade-1.0 force-response-1.0\n";
 
So the complete section looks like this:
while(<HTTPD_CONF>) {
    if (/^<VirtualHost [\d\.]+>$/ ... /^<\/VirtualHost>$/) {
        if ( /^<VirtualHost ([\d\.]+)>/o ) {
            # New section. Clean up.
            $ip = $1;
            @ssl_conf = ();
            $group = undef;
        }

        # Skip this bit, we don't need it now..
        next if (/^<VirtualHost/);

        # Just need to grab the group name out before we get on with
        # the real work.
        if ( /DocumentRoot \/home\/sites\/([^\/]+)\/web/ ){
            $group = $1;
        }

        # These two are for the rewrite options

        s/http/https/go if (/^Rewrite/);
        s/80/443/go if (/^Rewrite/);
        push @ssl_conf, $_;

        # Hardcoded, issues with mod_perl and cobalt modules.
        if (/^<\/Virtual/ and (-f "/etc/httpd/ssl/$group")) {
            $ret = ssl_cert_check("/home/sites/$group/certs/");
            if ($ret=~/^2/o) {
                $PerlConfig .= "Listen $ip:443\n";
                $PerlConfig .= "<VirtualHost $ip:443>\n";
####
                $PerlConfig .= "SetEnvIf User-Agent \".*MSIE.*\" \\n";
                $PerlConfig .= "        nokeepalive ssl-unclean-shutdown\\n";
                $PerlConfig .= "        downgrade-1.0 force-response-1.0\n";
####
                $PerlConfig .= "SSLengine on\n";
                $PerlConfig .= "SSLCertificateFile 
/home/sites/$group/certs/certificate\n";
                $PerlConfig .= "SSLCertificateKeyFile /home/sites/$group/certs/key\n";
                $PerlConfig .= join('', @ssl_conf);
            } elsif (ssl_cert_check("/home/sites/home/certs/") =~ /^2/ ) {
                $PerlConfig .= "Listen $ip:443\n";
                $PerlConfig .= "<VirtualHost $ip:443>\n";
####
                $PerlConfig .= "SetEnvIf User-Agent \".*MSIE.*\" \\n";
                $PerlConfig .= "        nokeepalive ssl-unclean-shutdown\\n";
                $PerlConfig .= "        downgrade-1.0 force-response-1.0\n";
####
                $PerlConfig .= "SSLengine on\n";
                $PerlConfig .= "SSLCertificateFile 
/home/sites/home/certs/certificate\n";
                $PerlConfig .= "SSLCertificateKeyFile /home/sites/home/certs/key\n";
                $PerlConfig .= join('', @ssl_conf);
            } else {
                print STDERR "Site $group has invalid certificate: $ret\n";
            }
        }
    }
}
close HTTPD_CONF;
