Unable to get cookie.ASPXAUTH value for login with PHP cURL

Question

I am almost 100% sure that I have all the messages on the Internet that contain the keywords asp login curl php.ASPXAUTH, but I could not find a solution. I'm more of a code hacker than an elegant developer, so I hope someone can help me.

I have a curl script that logs on two other sites to submit forms due to login. However, I recently tried using a variant of this script for a third website. It works until the first page returns after logging in, but then processes any further cURL calls, as if I hadn't logged in. I found (as I think) that this is because cookie.ASPXAUTH is not set. I have a cookie and a cookiejar setting in my cURL code and it successfully catches the .ASP.NET_SessionID file, but not the cookie.ASPXAUTH.

I noticed that I can see the cookie.ASPXAUTH value in the headers when I watch "Live HTTP headers", but I can not get my cURL script to easily return the header using this set-cookie. It seems that the cookie is set to 302 after logging in, and cURL does not handle this correctly. So I turned off CURLOPT_FOLLOWLOCATION and tried to handle the redirection myself, but I still can’t figure it out right (the server returns a really strange redirect URL, and I don’t think I am doing this part correctly)

But I would really appreciate it if someone could help me ...

Here is my code:

    //setup Curl
  $cookiename = substr($from,4,5);
  $cookiefile = $cookiename . ".txt";
  $ch = curl_init();
  curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
  curl_setopt($ch, CURLOPT_HEADER, 1); 
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (Windows; MSIE 6.0; U; Windows NT 5.1)");
  curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 0);
  curl_setopt($ch, CURLOPT_COOKIEFILE, $cookiefile);
  curl_setopt($ch, CURLOPT_COOKIEJAR, $cookiefile);

  //read login page
  curl_setopt($ch, CURLOPT_URL, "Login.aspx"); 
  $result = curl_exec ($ch);

  echo $result;



  // extract values for hidden form fields __REQUESTDIGEST __VIEWSTATE __EVENTVALIDATION fields

  //extract __REQUESTDIGEST
  $start = strpos($result,"id=\"__REQUESTDIGEST\" value=\"") + 28;
  $end = $start + 157;
  $rdigest = substr($result  , $start  , $end - $start );

  //extract __VIEWSTATE
  $start = strpos($result,"id=\"__VIEWSTATE\" value=\"") + 24;
  $end = $start + 16300;
  $vstate = substr($result  , $start  , $end - $start );
  $vstate = urlencode($vstate);

  //extract __EVENTVALIDATION
  $start = strpos($result,"id=\"__EVENTVALIDATION\" value=\"") + 30;
  $end = $start + 120;
  $event = substr($result  , $start  , $end - $start );
  $event = urlencode($event);


  //set login form values and login

  //curl_setopt($ch, CURLOPT_POST, true);
  curl_setopt($ch, CURLOPT_REFERER, 'Login.aspx');
  curl_setopt($ch, CURLOPT_HEADER, 1);
  curl_setopt($ch, CURLOPT_POSTFIELDS, '__REQUESTDIGEST=' . $rdigest . '&__VIEWSTATE=' . $vstate . '&__EVENTVALIDATION=' . $event . '&UserName=' . $from . '&Password=' . $password);
  $result = curl_exec ($ch);

  echo $result;

  //extract __redirect
  $start = strpos($result,"Location:") + 10;
  $end = strpos($result,".aspx") +5;
  $redirect = substr($result  , $start  , $end - $start );
                $redirect = "https://www.domain.com/" . $redirect;

  echo $redirect ."<br /><br />";

  echo $result;

  curl_setopt($ch, CURLOPT_URL, $redirect);
  $result = curl_exec ($ch);

  echo $result;

And here is the conclusion:

useragent cookie.ASPXAUTH ( ) cookie:)

:

curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (Windows; MSIE 6.0; U; Windows NT 5.1)");

:

curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2.13) Gecko/20101203 Firefox/3.6.13 ( .NET CLR 3.5.30729)");
