I am having some problems using cookies in some linux browsers. They only 
seem to be in existance for 1 or 2 pages after activation. Below is some 
code that works in windows but not linux:

on first page:
setcookie("cooky[Is_Admin]", $admin_var, time()+94608000, "/");

then on another page:
if ($cooky[Is_Admin]==yes)
{
...some code...
}

Please help.
