setcookie（）不在www.domain.tld上创建cookie，但在domain.tld上工作

Question

I've searched everywhere and tried everything. If you log in on http://r4ge.ro it works. If you go to www.r4ge.ro the cookie is read and works. If you log out, then try to log in on www.r4ge.ro the cookie is never created.

    $data = "name=" . $jucatoru . "&pass=" . md5($passw);
    $date_of_expiry = time()+60*60*24 ;
    setcookie ( $cookie, $data, $date_of_expiry, "/", ".r4ge.ro");
    echo "Succesfully logged in";
    exit();

I've checked and it's not a reading problem, the cookie doesn't exist if you try to log in from www.r4ge.ro. Tested on chrome and firefox (site doesn't work on IE)

This is how the logout is done

    $date_of_expiry = time() - 60 ;
    setcookie( $cookie, "nothing", $date_of_expiry, "/", ".r4ge.ro");
    echo "Succesfully logged out!

And this is how the cookie is read

$data = $_COOKIE[$cookie];
parse_str($data, $output);
$name = $output['name'];
$pass = $output['pass'];

Test credentials: test : test1 if you want to try it out yourselves

Answer 1

I'll go ahead and answer this even tho the answer is unsatisfactory as hell.

I've written a letter to my hosting provider and they provided two solutions:

• Create two separate cookies for www and non www (dumb)

• Use .htaccess to redirect from www to non www (still dumb but apparently everyone does it because hurr durr duplicate content[you can even try www.stackoverflow.com])

To save everyone with this problem another google search, here's the script you need to add to .htaccess to redirect from www to non www without specifying domain.

RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC]
RewriteRule ^(.*)$ http://%1/$1 [R=301,L]

If someone knows the answer to the cookie issue, please post that too.
