HTTP Cookie Manager handles incoming cookies automatically, it:

1. Extracts the cookies from the Set-Cookie response header
2. On subsequent requests if domain and path of the request matches the ones of the cookie(s) the cookie is being added to the request's Cookie header

So there is no need to use any post processors for extracting the cookies.

If the cookie manager is "not working" most probably there is a problem with the cookie, i.e. it's expired or domain of the request is different or something like this. If you want to see what's going on under the hood you can increase JMeter logging verbosity for the cookie manager by adding the next line to log4j2.xml file:

<Logger name="org.apache.jmeter.protocol.http.control" level="debug" />

if there are issues with cookies and JMeter is unwilling to add the cookie you can force it by

1. Choosing less restrictive policy, i.e. netscape

   

2. Adding the next line to user.properties file:

   CookieManager.check.cookies=false
