nginx相关的一些记录

http redirect to https:

        if ($http_cf_visitor ~ '"scheme":"http"'){
            rewrite ^/(.*)$ https://$http_host$1 last;
        }
        proxy_pass http://scholar.google.com;
        proxy_set_header Host scholar.google.com;

when 403 404 error then query node_app:

    location / {
        root   /www/www.site.com/public_html;
        index  index.html;

        location ~ /$ {
            error_page 403 404 = @node_app;
        }

        location = /index.html {
            expires 5m;
        }
    }

node_app:

    location @node_app {
        proxy_pass   http://127.0.0.1:9000;
        proxy_set_header Host $http_host;
    }

动态反向代理：

resolver 223.5.5.5;

    location ~ /(\w+)(.*)$ {
        proxy_pass http://m.$1.domain.com$2?$args;
        proxy_set_header Host m.$1.domain.com;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header User-Agent $http_user_agent;
        sub_filter \"/ \"http://$http_host/$1/;
        #sub_filter \"http://m.$1.domain.com/ \"http://$http_host/$1/;
        sub_filter_once off;
    }
