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

I should have been a little more clear in my question, but we got this fixed. Here is our solution:

Http Cookie Manager
Thread A - 1 Thread - 1 Loop Count
  - Login Page
      - BeanShell PostProcessor
            - props.put("MyCookie","${COOKIE_<INSERT ACTUAL COOKIE NAME>}");
Thread B - 50 Threads - Infinite Loop Count
  - BeanShell PreProcessor 
      - import org.apache.jmeter.protocol.http.control.CookieManager;
        import org.apache.jmeter.protocol.http.control.Cookie;
        CookieManager manager = sampler.getCookieManager();
        Cookie cookie = new Cookie("<INSERT ACTUAL COOKIE NAME>",props.get("MyCookie"),"<INSERT DOMAIN NAME>","<INSERT COOKIE PATH>",false,0);
        manager.add(cookie);
  - Page to hit
  - Another page to hit, repeat as needed

Then there is a configuration change for JMeter needed:

Open up the jmeter.properties file and go to the line "CookieManager.save.cookies=false" and make it = true.

This will allow the login cookie in the first thread to be used in the second thread.

Answer 2

CookieManager does not share cookies between threads. For some reason @ClarenceKlopfstein's method didn't work for me (jmeter 3.0). For some reason "${COOKIE_<INSERT ACTUAL COOKIE NAME>}" didn't seemed to evaluate the string passed.

So, here's another solution to do a Login, and then pass the .ASPXAUTH cookie. It should work without any configuration changes: In a setUp Thread Group (important):

BeanShell PostProcessor:
 import org.apache.jmeter.protocol.http.control.CookieManager;
 import org.apache.jmeter.protocol.http.control.Cookie;

 CookieManager manager = ctx.getCurrentSampler().getCookieManager();
 Cookie cookie = manager.get(3); //Find the '.ASPXAUTH' cookie
 log.info("Cookie:" + cookie);
 props.put("MyCookie",cookie.getValue());

Then in a normal Thread Group:

BeanShell PreProcessor:
 import org.apache.jmeter.protocol.http.control.CookieManager;
 import org.apache.jmeter.protocol.http.control.Cookie;
 CookieManager manager = sampler.getCookieManager();
 Cookie cookie = new Cookie(".ASPXAUTH",props.get("MyCookie"),"<DOMAIN>","/",false,0);
 manager.add(cookie);
