Can a server ignore PHP curl sessions? - php

Question

It looks like a webserver is ignoring my cookies. (used in PHP curl)
Getting the cookies works fine, but returning doesn't work. When I go to the website with my browser and remove the cookies I get the exact same behaviour.
How can I solve this? Does it have anything to do with the https?
Code:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://example.com/createAccount.jsp');
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
curl_setopt($ch, CURLOPT_COOKIEFILE, "/var/www/ajax/Cache/Sessions/cookie.txt");
curl_setopt($ch, CURLOPT_COOKIEJAR, "/var/www/ajax/Cache/Sessions/cookie.txt");
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
$result = curl_exec($ch);
curl_close($ch);
$ch = curl_init();
$data = array('_dyncharset' => 'UTF-8',
'_DARGS' => '/createAccount.jsp',
'firstName' => $firstname,
'login' => $email,
'lastName' => $lastname);
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));
curl_setopt($ch, CURLOPT_URL, 'https://example.com/createAccount.jsp?action=createAccount');
curl_setopt($ch, CURLOPT_COOKIEFILE, "/var/www/ajax/Cache/Sessions/cookie.txt");
curl_setopt($ch, CURLOPT_COOKIEJAR, "/var/www/ajax/Cache/Sessions/cookie.txt");
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
curl_setopt($ch, CURLOPT_HEADER, true);
$result = curl_exec($ch);
curl_close($ch);

Answer 1

make sure the CURLOPT_COOKIEJAR file is writeable by the server process (that executes the php script).
if that fails you can simply re-use the same instance of curl just drop the
curl_close($ch);
$ch = curl_init();

Answer 2

Remove below line from your first curl request. And it should work for you:
curl_setopt($ch, CURLOPT_COOKIEFILE, "/var/www/ajax/Cache/Sessions/cookie.txt");
CURLOPT_COOKIEFILE is used to send cookie to server from a file. So removing this line will mean sending no cookie. So server will not notice any previous visit :-)
