jMeter: How to save a variable as cookie

Question

I'm testing a site in jMeter 5.1 that once returns a header "X-Csrf-Token" and expects the value to be found in a cookie named __csrf_token-1.

The HTTP Cookie manager alone is no help, as I need to write a response header (not a recieved cookie) into a cookie.

How can change cookie values on the fly?

Thanks!

Answer 1

1. Extract the cookie from the previous response using i.e. Regular Expression Extractor configured like:

   

   double check that the extraction succeeds using Debug Sampler and View Results Tree listener combination

2. Add HTTP Cookie Manager as a child of the next request and configure it to send __csrf_token-1 cookie with the value of ${token}

   

   make sure to provide correct Domain and Path values, if you don't know them - change "Cookie Policy" to netscape
