How to disable cookies in Postman Application

I believe this is still an open issue on the project and the only way that i’ve been able to do, is delete them through the UI.

Go to "settings" tab and disable "cookie jar" and "follow redirects".

Thus, Postman will act as fetch in node-js for instance. It will acts as it is the first attempt to login (or whatever) and you'll see a fresh response every time.

You can use version 6.1.3, which had a bug in it which prevented to send cookies on subsequent request. See https://community.getpostman.com/t/postman-no-longer-send-cookie-with-subsequent-requests/1723

But it's hard to get your hand on that version, it is not on https://www.getpostman.com/downloads/release-notes because they only show major versions 7.
