[英]Set Vary: Accept-Encoding Header (nginx)
I have an nginx server and can't seem to find any information on how to send Vary: Accept-Encoding headers for CSS and JS files.我有一个 nginx 服务器,似乎找不到任何有关如何发送 Vary: Accept-Encoding headers for CSS 和 JS 文件的信息。 Does anyone have info about this?有人有这方面的信息吗?
Thanks!谢谢!
This is from the nginx documentation .这来自 nginx文档。
gzip_vary syntax: gzip_vary on|off default: gzip_vary off context: http, server, location
Enables response header of
"Vary: Accept-Encoding"
.启用"Vary: Accept-Encoding"
的响应 header 。 Note that this header causes IE 4-6 not to cache the content due to a bug (see 2 ).请注意,此 header 会导致 IE 4-6 由于错误而无法缓存内容(请参阅2 )。
There if you just add gzip_vary on;
如果你只是添加gzip_vary on;
it should do it's job.它应该做它的工作。
Also make sure you have any one of the directives gzip, gzip_static, or gunzip are active.还要确保您有任何一个 gzip、gzip_static 或 gunzip 指令处于活动状态。
Inside the server {
of the domain/subdomain that you want to set it, add在要设置的域/子域的server {
中,添加
gzip on;
gzip_min_length 1100;
gzip_buffers 4 32k;
gzip_types text/plain application/x-javascript text/xml text/css;
gzip_vary on;
Save the file and restart nginx.保存文件并重启 nginx。
Simple.简单的。 In Nginx conf:在 Nginx 配置文件中:
vim /etc/nginx/nginx.conf
Add the following near the bottom under the section:在该部分的底部附近添加以下内容:
##
# Gzip Settings
##
gzip on;
gzip_disable "msie6";
# gzip_vary on;
# gzip_proxied any;
# gzip_comp_level 6;
# gzip_buffers 16 8k;
# gzip_http_version 1.1;
# gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript;
Just uncomment the gzip_vary on;
只需取消注释gzip_vary on;
parameter and restart or reload nginx service:参数并重新启动或重新加载 nginx 服务:
service nginx restart
This should fix the issue.这应该可以解决问题。 If you are running an old version of nginx, you may need to enable gzip on;
如果您运行的是旧版本的 nginx,您可能需要启用gzip on;
, as this is required for the vary header to work. ,因为这是使不同的 header 工作所必需的。
I hope this helps.我希望这有帮助。 FYI, this applies to all server/site conf files unless overwritten in their own respective server blocks.仅供参考,这适用于所有服务器/站点配置文件,除非在它们各自的服务器块中被覆盖。 server {}

If you've tried the other answers and are still seeing vary off (eg if you are testing speed of your page using GTMetrix), the following might help:如果您已经尝试了其他答案并且仍然看到变化(例如,如果您正在使用 GTMetrix 测试页面的速度),那么以下可能会有所帮助:
Make sure all your gzip_types are also set in /etc/nginx/nginx.conf http section.确保您的所有 gzip_types 也在 /etc/nginx/nginx.conf http 部分中设置。
The server block in /etc/nginx/sites-available/* is one place where you can set the vary header and gzip_types, but depending on how you have your site setup you may be processing and returning files before they reach that bit of config. /etc/nginx/sites-available/* 中的服务器块是您可以设置不同的 header 和 gzip_types 的地方,但根据您的站点设置方式,您可能会在文件到达该配置位之前处理和返回文件.
In /etc/nginx/nginx.conf you will find an 'http' section - in here, there is also a gzip_types and gzip_vary.在 /etc/nginx/nginx.conf 中,你会找到一个“http”部分——在这里,还有一个 gzip_types 和 gzip_vary。
For me - CSS and JS are static files and were being served up before hitting the (wordpress) nginx sites-available file (I have varnish in front of it).对我来说 - CSS 和 JS 是 static 文件,并且在点击(wordpress)nginx 站点可用文件(我在它的前面有varnish)之前被提供。
So adding the full list of gzip_types to the http section in nginx.conf fixed my issue.因此,将 gzip_types 的完整列表添加到 nginx.conf 中的 http 部分解决了我的问题。
