Q: php cURL cookies/authentication not sticking? I am learning cURL in PHP, and need to authenticate to a web page, and store the session in a cookie.  I am able to log in just fine, but when I try to use the cookie to load another page, I don't get any output.  It's late, and I'm sure there's something stupid I'm missing, but I dont think I'll be able to sleep without this working..
$curl_p = curl_init($auth_url);
curl_setopt($curl_p, CURLOPT_COOKIEJAR, $svck);
curl_setopt($curl_p, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl_p, CURLOPT_RETURNTRANSFER, 1);
$cres_auth = curl_exec($curl_p);

if(!preg_match("/Successful/i",$cres_auth))
    {
    ?><pre><?
            print_r("Login was unsuccessful.  URL passed was:");
    ?><br><br><?
            print_r($auth_url);
    ?></pre><?
    }else
    {
    ?><pre><?
            print_r("Login was successful.");
    ?></pre><?

    $curl_p = curl_init($data_url);
    curl_setopt($curl_p, CURLOPT_COOKIEFILE, $svck);
    curl_setopt($curl_p, CURLOPT_URL, $data_url);
    $cres_data = curl_exec($curl_p);
    echo $cres_data;
    }

Given the proper credentials, I get a "Login was successful", otherwise it fails.  If successful, I don't get anything else; do i need to do curl_close() and re-init?  Thanks!

Not sure if it matters, but here is the header for the response when logging in normally (through a browser):

I was logging into https://.. and did not include curl_setopt($curl_p, CURLOPT_SSL_VERIFYPEER, false); in the if().. block.  Adding it appears to have worked.  Thanks again everyone!
