How many vars should there be in a cookie?

Ted

While using cURL with some site, I noticed that some files that I requested actually used several variables from the cookie I set up with curl.

Here’s a snapshot:

But when I check my cookie file all it reads is just one value for ASP.NET_SessionId:

www.*******.***  FALSE  /  FALSE  0  ASP.NET_SessionId  ddj24l55lfu11nb1lhuflw55

Of course, the values from the snapshot are taken from my browser (Internet Explorer F12), and that cookie contains Three variables (not one).
Internet Explorer F12 cookie variables Name/Values:

NAME  ASPSESSIONIDSACRDADD 
VALUE  LOONCEMDHCGEJOANEGHHFAFH 

NAME  ASPSESSIONIDSCBRABDC 
VALUE  CMONJEMDNICPNPNFICLAPMFM 

NAME  ASPSESSIONIDQACSBADC 
VALUE  MCBOGLCCKNIDDBOADNMPCLCD 

this is my CURL settings for cookies:

$cookiefile = "d:/cookie.txt";

curl_setopt($curl, CURLOPT_COOKIESESSION, 1);
curl_setopt($curl, CURLOPT_COOKIEFILE, $cookiefile);
curl_setopt($curl, CURLOPT_COOKIEJAR, $cookiefile); 

What is it that I may be missingin cURL ?

Thanks!
