Sharing cookie values between thread groups in JMeter

Question

I have the following setup:

Thread A
  - Http Cookie Manager
  - Login Page
Thread B
  - Http Cookie Manager
  - Page to hit
  - Another page to hit
         


        

Answer 1

The answer above really helped me but the HTTP cookie Manager was missing the detail that I required to get it to work. By setting the cookie manager as below, it worked for me

Http Cookie Manager
NAME   $
VALUE  ${COOKIE_}    
DOMAIN ${SITE}   
PATH    /
Thread A - 1 Thread - 1 Loop Count
....
Thread B - 50 Threads - Infinite Loop Count
....
