Accept cookies using cURL?

Question

I've been trying to get the contents of a webpage using cURL, but have trouble getting cURL to accept cookies. For example, on Target.com, when I cURL it, it still says that I have to enable cookies.

Here is my code:

$url = "http://www.target.com/p/Acer-Gateway-15-6-Laptop-PC-NV57H77u-with-320GB-Hard-Drive-4GB-Memory-Black/-/A-13996190#?lnk=sc_qi_detailbutton";
$ch = curl_init();    // initialize curl handle
curl_setopt($ch, CURLOPT_URL,$url); // set url to post to
curl_setopt($ch, CURLOPT_FAILONERROR, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);// allow redirects
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1); // return into a variable
curl_setopt($ch, CURLOPT_TIMEOUT, 10); // times out after 4s
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7; rv:11.0) Gecko/20100101 Firefox/11.0"); 
$cookie_file = "cookie1.txt";
curl_setopt($ch, CURLOPT_COOKIESESSION, true);
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file);
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file);
$result = curl_exec($ch); // run the whole process
curl_close($ch); 
echo $result;

What else am I missing? The cookie1.txt file is 077 permission, by the way.

Solution

077 is an malformed permission setting, this means the owner (probably apache) has no access. Try setting it to 644 (owner has read/write) as it's only a file.
