How to set SameSite attribute?

It turns out that using setHeader() method remove all previous headers with the same name so I just create simple for loop in doFilter() method. It adds SameSite=Strict attribute to every cookie that is set.

boolean firstHeader = true;
for (String header : cookiesHeaders) {
    if (firstHeader) {
        httpResponse.setHeader("Set-Cookie",
                String.format("%s; %s", header, "SameSite=Strict"));
        firstHeader = false;
        continue;
    }
    httpResponse.addHeader("Set-Cookie",
            String.format("%s; %s", header, "SameSite=Strict"));
}
