handle cookie through XML web server
<p>I am dealing with XML API, where according to the document, i need to login XML call first before making secure(HTTPS) calls. 
e.g. to make login call (http://calllogin.do?username=test&amp;password=password).
once i am successfully logged in, third party system will write cookie.
everytime i make https call third party system will read security details from cookie.
But sytsem i am designing is like "man in the middle".
In a nutshell - 
1 - user logs in to my system
2 - sends query to my server
3 - my web application reads the querystring and send request to third party system, process the response and send to browser. 
therefore the main problem is how can I handle this cookie problem.
I will be using c# as my web application
Hopefuly I was able to explain my scenario</p>
