Perl + IE + Cookies

[jebusCL]

Hi, i'm writing an script that need to register three cookies at the same time from three differents servers located under the same domain. the code that i made works perfectly in Mozilla, but under IE i have the problem that the cookies are overwritten, wich means that only one cookie remains in the client and is the last that i sent. plus, i can't read the cookie written. the script is not CGI the code that i'm using is like this

sub setCookie
{
my ($expires, @cookies) = @_;
my ($header);
my ($cookie,$value, $char);

my @cookie_encode_chars = ('\%', '\+', '\;', '\,', '\=', '\&', '\:\:',
+ '\s');
my %cookie_encode_chars = ('\%','%25','\+','%2B','\;','%3B','\,','%2C'
+,'\=', '%3D','\&','%26','\:\:','%3A%3A','\s','+');
my @cookie_decode_chars = ('\+', '\%3A\%3A', '\%26', '\%3D', '\%2C', '
+\%3B', '\%2B', '\%25');
my %cookie_decode_chars = ('\+',' ','\%3A\%3A', '::','\%26','&','\%3D'
+,'=','\%2C', ',','\%3B',';','\%2B','+','\%25','%');

while(($cookie,$value)=@cookies) {
foreach $char (@cookie_encode_chars) {
$cookie =~ s/$char/$cookie_encode_chars{$char}/g;
$value=~ s/$char/$cookie_encode_chars{$char}/g;
}
if ( $expires)
{
$header.= "Set-Cookie: $cookie=$value; expires = $expires; path=/;\n";
}
shift(@cookies);
shift(@cookies);
}
$cookie =1;
return $header;
}


sub GetCook
{
my (@cookies, %cookie_hash, $cookie, $key, $val);

@cookies = split (/; /,$ENV{'HTTP_COOKIE'});

foreach $cookie (@cookies)
{
($key, $val) = split (/=/,$cookie);
$cookie_hash{$key} = $val;
}
return keys(%cookie_hash);
}

where could be the problem?? thanks in advance
