Q:

Unauthorized Access when cURL PHP request with cookies

I am trying to access a page, say http://www.domain.com/profile.  The action and login urls are the same, and I am trying to save cookies to http://www.example.com/cookies.txt for authentication.  Here is the code I'm using:
$loginURL = 'http://www.domain.com/login';
$COOKIE_FILE = 'http://wwww.example.com/cookies.txt';
$postValues = array(
    'username' => 'myusername',
    'password' => 'mypassword'
);
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $loginURL); 
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query($postValues));
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl, CURLOPT_COOKIEJAR, $COOKIE_FILE);
curl_setopt($curl, CURLOPT_USERAGENT, 'Chrome/35.0.2309.372');
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_REFERER, $loginURL); 
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);
curl_exec($curl);
if(curl_errno($curl)){throw new Exception(curl_error($curl));}

// now we are logged in, attempt to access a password-protected page
curl_setopt($curl, CURLOPT_URL, 'http://www.domain.com/profile');
curl_setopt($curl, CURLOPT_COOKIEJAR, $COOKIE_FILE);
curl_setopt($curl, CURLOPT_USERAGENT, USER_AGENT);
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
echo curl_exec($curl);

It seems like the curl requests are successful, but I am getting echoed a page from the server saying "Unauthorized Access". I don't think my cookies system is working correctly? How can I check that? How do I fix it?

A:

Set CURLOPT_COOKIEFILE to same path as CURLOPT_COOKIEJAR. curl reads from file and writes to jar.
ETA: One likely reason your script doesn't work is that you don't send the cookie data from the first request in the second request.
