Proxyman version? (Ex. Proxyman 1.4.3)

3.0.0

macOS Version? (Ex. mac 10.14)

Snippet Request

Given an ongoing or incoming request with multiple cookies, I'd like to override a single cookie. This would be very useful 🙏

Because Cookie is just a Header, you can simply override as the same way you do with the Header.

function onRequest(context, url, request) {
    var cookies = request.headers["Cookies"];
    cookies.replace("AAA", "New Value")
    request.headers["Cookies"] = cookies;
    return request;
}
