In the override attributes mode, the existing cookie along with its attributes will be completely replaced by the value and the attributes that you have set in ModHeader.

If you want to simply change the existing set-cookie attribute while retaining its value, you can click on Empty cookie: remove chip to change the behavior to Empty cookie: retain value, update attributes.

You can use regex cookie name match to modify multiple cookies at the same time.

  1. To enable regex cookie name matching mode, click on the button.
  2. Enter a regex expression in the cookie name field. For example, .*foo.* will match foobar as well barfoo.
  3. The matching cookies will have their values and/or attributes overridden.

NOTE: If regex mode is enabled and there are no matching cookies, then no new cookie will be added. This is different from non-regex mode where a new cookie header will be added if none is matched.
