Find requests with Set-Cookie headers in DevTools Network tab

To find requests that set a specific cookie, use the set-cookie-name filter in your Network tab:

set-cookie-name:YOUR_COOKIE_NAME

This works in Chromium browsers and Firefox (but unfortunately not in Safari).

See also: set-cookie-domain and set-cookie-value.

For a full list of available filters, see Chrome DevTools > Network features reference.
