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

Why not to add Http Cookie Manager to the Test Plan level instead of Thread Group one and group all the samplers in one thread group?

Test Plan
    Http Cookie Manager
    Thread Group
        - Login Page
        - Page to hit
        - Another page to hit

This should solve your problem without any other extra samplers.
Or maybe there are some objective reasons to implement the way you've done?

...Please look onto this too.
