How to set SameSite cookie attribute using Apache configuration?

问题

I am not able to see SameSite=Strict using builtin developer tools in the “Application” tab.

I have added below Header code in Apache configuration

Header always edit Set-Cookie (.*) "$1;SameSite=Strict"
Header edit Set-Cookie ^(.*)$ $1;SameSite=Strict

Please let me know how to set SameSite=Strict using above settings.

回答1:

For apache2 >= 2.2.4

Header edit Set-Cookie ^(.*)$ $1;HttpOnly;Secure;SameSite=Strict

For apache2 lower than 2.2.4

Header set Set-Cookie HttpOnly;Secure;SameSite=Strict

In my local environment (Apache 2.4) after enabling mod_headers I was able to achive this by adding directives like below in my vhost:

<ifmodule mod_headers.c>
Header always edit Set-Cookie (.*) "$1; SameSite=strict"
</ifmodule>

Where is the difference? Why it didn't work for you? Mayby its lack of "space" after semicolon?

<ifmodule mod_headers.c>
# always is similar to "onerrors"
        Header always edit Set-Cookie (.*) "$1; SameSite=strict"
# success is similar to http 2xx response code
        Header onsuccess edit Set-Cookie (.*) "$1; SameSite=strict"
# remove duplications (apache sends from both tables always and onsuccess)
        ## https://www.tunetheweb.com/security/http-security-headers/secure-cookies/
        #Strip off double SameSite=strict settings as using above you can sometimes get both
        Header edit Set-Cookie ^(.*);\s?SameSite=strict;?\s?(.*);\s?SameSite=strict;?\s?(.*)$ "$1; $2; $3; SameSite=strict"

        #Strip off double ;; settings
        Header edit Set-Cookie ^(.*);\s?;\s?(.*)$ "$1; $2"

</ifmodule>

[stack discusion] (httpd duplicate Access-Control-Allow-Origin with "Header always set")
