I am trying to use the HTTP_IF_MODIFIED_SINCE header in my app to determine if resources are stale/fresh and render 200/304 in those cases. In my dev environment everything works fine but I can t for the life of me get it to work in production.
我正在使用旅客3.0.11和Nginx1.0.13。
As you see below, I tried proxy_pass_header, proxy_set_header, passenger_pass_header and passenger_set_cgi_param. The last one actually sets a HTTP_IF_MODIFIED_SINCE header but it is empty... Any help/ideas would be greatly appreciated!
我的想象力:
server {
listen 80 default_server;
root /home/rails/myapp/current/public;
passenger_enabled on;
charset utf-8;
proxy_pass_header If-Modified-Since;
proxy_set_header If-Modified-Since $http_if_modified_since;
passenger_pass_header If-Modified-Since;
passenger_set_cgi_param HTTP_IF_MODIFIED_SINCE $http_if_modified_since;
if (-f $document_root/system/maintenance.html) {
rewrite ^(.*)$ /system/maintenance.html break;
}
location ~ .(aspx|jsp|cgi)$ {
return 410;
}
location ~ ^/(assets)/ {
# http://guides.rubyonrails.org/asset_pipeline.html#server-configuration
# gzip_static on;
expires 1y;
add_header Cache-Control public;
add_header Last-Modified "";
add_header ETag "";
break;
}
}
