OK I got it working. Thanks for your help.

Just in case it helps someone else. Here is my code to login to a
website and download txt file using https
           
          $url = "https://...";
        $postFields = "username=user&password=pass";
        $ch = curl_init();
        curl_setopt($ch,CURLOPT_URL,$url);
        curl_setopt($ch,CURLOPT_COOKIEJAR,"cookie.txt");
        curl_setopt($ch,CURLOPT_COOKIEFILE,"cookie.txt");
        curl_setopt($ch,CURLOPT_POST,TRUE);
        curl_setopt($ch,CURLOPT_POSTFIELDS,$postFields);
        curl_setopt($ch,CURLOPT_FOLLOWLOCATION,TRUE);
                
            ob_start();
                curl_exec($ch);
                ob_end_clean(); // stop preventing output

                
            $url = "https:// .. file.txt"
                 curl_setopt($ch,CURLOPT_URL,$url); // same curl handle
                 curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
             ob_start();
                 $response = curl_exec($ch);
                 ob_end_clean();
                        
        cheers

My guide to successful login:

1. Use LiveHTTPHeaders with your browser and do eveything you want to
do.

2. Use the curl command line tool and its --trace-ascii option to login.

3. Compare that the outputs from 1) and 2) are sufficiently similar. As
long
as they differ and the site still complains you can continue mimicing
the
browser even closer, using the output from 1) as a guide.
