title: Authenticating ChatBot (Microsoft Bot Framework) using cookies from different website in same domain?
body: <p>I need to authenticate my user in chatbot ,using cookies in my website
  eg. I have a website "portal.b.com" hosted on an azure Virtual Machine  ,</p>
  
  <p>So when my user logs into my website I cookies are stored 
  When he/she clicks On the bot , the bot should be aware about the user details.</p>
  
  <p>eg. Hi "User_Name"</p>
  
  <p>1) I have apis to get the user details , 
  2) I just dont want to ask user to sign in separately into the bot.
  3) I use a session id and other cookies in my website
  4) I have currently implemented the bot in Node JS
  5) I have web application in C#</p>
  
  <p>How can I implement above scenario?</p>
  
  <p>Thanks</p>
