title: Is it possible to send a cookie with a SMSMessage using the Twilio-csharp / TwilioRestClient?
body: <p>I am creating outbound SMS communication and need to set a cookie so I can track the conversation thread.  I'm using the Twilio-charp client and did not see a way to set a cookie or and http header.  Is this possible or do I need to pursue a different route?</p>
  
  <p><strong>Edit:</strong></p>
  
  <p>I need to elucidate here.  In my scenario I need to set a cookie with a transaction id that needs to included in the originating outbound message.  For example I will be creating an SMS message that will request a response from the user:  "Text (1) to approve, (2) to decline".</p>
  
  <p>The Twilio sample code details a page that receives a message, checks for a cookie, then creates one if it does not already exist.  In my scenario I need the cookie to be in the outbound message.</p>
