Tag: Stick

Well, I was looking at the Instagram website’s network tab and I noticed that it has a Vary header with 3 values, something that made me think about my website’s network tab.

In the network tab of my website, there are two Vary headers, but I would like to have only one, just like on Instagram, this seems to be more professional.

I looked at my code and found it a bit complicated, I don’t know what to do to get where I want..

Please see my server code and tell me if there is a possibility to do it like on Instagram?

Server Code

map $http_accept_language $language_by_header {
    ~en.*pt(*SKIP)(*F)|pt  pt; # when "pt" substring present and not preceded with "en"
    ~pt.*en(*SKIP)(*F)|en  en; # when "en" substring present and not preceded with "pt"
    default                en; # or use "pt" if you want the Portuguese to be default
}

map $cookie_language $used_language {
    pt                     pt;
    en                     en;
    # detect language from "Accept-Language" header when no "language" cookie present
    default                $language_by_header;
}

server {

    root /var/www/example.com/html/$used_language;
    try_files $uri $uri/ @extensionless-php;
    index index.php



    server_name example.com www.example.com;

    charset utf-8;

    error_page 403 http://example.com/forbidden.html;
    error_page 404 =301 http://example.com/404.html;


    #It is used for cache policy
    location ~* .(?:ico|css|js|gif|jpe?g|png|webp)$ {
        expires 365d;
        add_header Vary Accept-Encoding;
        access_log off;
    }


    location ~ .php$ {
        root /var/www/example.com/html/$used_language;
        add_header Vary "Accept-Language";
        add_header Strict-Transport-Security "max-age=31536000" always;
        include snippets/fastcgi-php.conf;
        fastcgi_pass unix:/run/php/php7.4-fpm.sock;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        internal;
    }
