Unable to get Response Header Cookie and set it to another Request Body in Jmeter script

Question

Not able to pass Response Header (Set-Cookie value) to another request Body in order to place a reservation.

To place a reservation i need to get HoldReservation cookie from Reservedate API but when getting all cookies in Beanshell postprosessor and sending it to Beanshell preprosessor is not helping.

I have Cookie Manager at Thread level but that is not getting this cookie that is generated in the middle of the execution.

I want to get just the HoldReservation and expires from the below Cookie: Set-Cookie: HoldReservation=; expires=Thu, 15-Apr-2021 17:40:20 GMT; path=/; secure

Answer 1

The easiest way is just adding the next line to the user.properties file:

CookieManager.save.cookies=true

and on next JMeter restart you will be able to access the cookie as `${COOKIE_HoldReservation} where required. More information: HTTP Cookie Manager Advanced Usage - A Guide

If you still want to do this using regular expressions here is an example setup:

textual representation of the regular expression:

Set-Cookie:\s*HoldReservation=(.+?);
