PHP - CURL - redirecting to main domain after login, which I don't want

I am using curl to logging in to a aspx file. I have managed to login but after login, it goes to the main site.
for example,

$url="https://www.test.com"
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_COOKIEJAR, $ckfile);
curl_setopt($ch, CURLOPT_COOKIEFILE, $ckfile);
curl_setopt($ch, CURLOPT_HEADER, FALSE);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, false);
curl_setopt($ch, CURLOPT_REFERER, $url1);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_STDERR, $f);
curl_setopt($ch, CURLOPT_USERAGENT, $useragent);

curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postfields);
$ret = curl_exec($ch); // Get result after login page.
curl_close($ch);

after this it redirects to the main site, while I need to stay on localhost and get another page. if I give Followlocation=1 it goes to the main site and if I give Followlocation=0 it says 'Object Moved here"

I want the output stored in a variable after login.

 

try to comment this line curl_setopt($ch, CURLOPT_REFERER, $url1);
