What I mean by session cookie is one that is set but then deleted once
you would leave that web site.

Example If I where to use the Perl code below to set a cookie, it would
be read in perl with the variable $ENV{'HTTP_COOKIE'} but not with
print_r($_COOKIE);
#################
#Start Perl Code
#################
$user = "test";
$pass = "pass";
$cookie = &SetCookie("susername", $user, 0);
print $cookie;
$cookie = &SetCookie("spassword", $pass, 0);
print $cookie;

sub SetCookie() {
  my ($name,$value,$expires,$path,$domain) = @_;

  $name=&CookieRE($name);
  $value=&CookieRE($value);

  $expires=$expires * 24 * 60 * 60;

  my $expire_at=&CookieDate($expires);
  my $namevalue="$name=$value";

  my $COOKIE="";

  if ($expires != 0) {
     $COOKIE= "Set-Cookie: $namevalue; expires=$expire_at; ";
  }
   else {
     $COOKIE= "Set-Cookie: $namevalue; ";
   }
  if ($path ne ""){
     $COOKIE .= "path=$path; ";
  }
  if ($domain ne ""){
     $COOKIE .= "domain=$domain; ";
  }
   
  $COOKIE .= "\n";

  return $COOKIE;
}


sub CookieDate() {
  my ($seconds) = @_;

  my %mn = ('Jan','01', 'Feb','02', 'Mar','03', 'Apr','04',
            'May','05', 'Jun','06', 'Jul','07', 'Aug','08',
            'Sep','09', 'Oct','10', 'Nov','11', 'Dec','12' );
  my $sydate=gmtime(time+$seconds);
  my ($day, $month, $num, $time, $year) = split(/\s+/,$sydate);
  my    $zl=length($num);
  if ($zl == 1) { 
    $num = "0$num";
  }

  my $retdate="$day $num-$month-$year $time GMT";

  return $retdate;
}


sub CookieRE() {
  my($retval) = @_;

  $retval=~s/\;//;
  $retval=~s/\=//;

  return $retval;
}
#################
#End Perl Code
#################

Where as for example if I used this java script code to set cookies,
will apear in both the $ENV{'HTTP_COOKIE'} and with print_r($_COOKIE);


<SCRIPT LANGUAGE = "JavaScript">
<!-- 


function setCookie(name, value, expires) {
document.cookie = name + "=" + escape(value) + "; path=/" +
((expires == null) ? "" : "; expires=" + expires.toGMTString());
}


function getValue(element) {
var value = getCookie(element.name);
    if (value != null) element.value = value;
}

function setValue(element) {
setCookie(element.name, element.value, exp);
}

var exp = new Date();                                   
exp.setTime(exp.getTime() + (1000 * 60 * 60 * 24 * 31));

function delCookie(name) {
document.cookie = name + "=; expires=Thu, 01-Jan-70 00:00:01 GMT" +  ";
path=/";
}

//-->

</SCRIPT>

<form OnSubmit = "setValue(document.form.username) +
setValue(document.form.password);">
Etc...


Hopefully that maks sense, I know the last thing you want to do is read
perl code but it will give you an example of what I mean.

Not a bug. (define 'session cookie' ?)

print_r($_COOKIE);
Does not print Session cookies. IE from another global source.

example in Perl if you use the variable it shows all cookies including
session ones:
$ENV{'HTTP_COOKIE'}

print_r($_COOKIE);
Will show the same variables as $ENV{'HTTP_COOKIE'} minus any session
cookies. I looked through this site but saw no documentation on this
and am thinking it is posibly a bug in PHP.

Thanks for your attention to this.
