我在HTPC上安装了Transmission作为BT下载工具，并安装了WebUI通过浏览器进行管理，由于家庭对外开放的端口都由一台Linux机器做的Nginx反向代理，所以涉及到了用Nginx反代Transsmission的问题。

首先尝试了一下常规的反向代理设置，无法工作，研究了之后发现网页登录Transmission后是有一个Session-Id的，需要在配置文件中添加一个header，于是合理利用了一下搜索引擎。

从Github中找到了一段代码：

upstream transmission {
    server 127.0.0.1:9091; #Transmission
}

server {
    listen 443 ssl http2;
    server_name example.com;
    auth_basic "Server Restricted";
    auth_basic_user_file /var/www/myWebSite/web/.htpasswd;

    # Path to the root of your installation
    error_log /var/www/myWebSite/logs/error.log;
    access_log /var/www/myWebSite/logs/access.log;

    ### SSL cert files ###
    ssl_certificate /var/www/myWebSite/ssl/advert.crt;
    ssl_certificate_key /var/www/myWebSite/ssl/advert.key;

    ### Add SSL specific settings here ###
    ssl_session_timeout 10m;
    ssl_protocols SSLv3 TLSv1 TLSv1.1 TLSv1.2;
    ssl_ciphers ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv3:+EXP;
    ssl_prefer_server_ciphers on;

    location / {
        return 301 https://$server_name/transmission/;
    }

    location ^~ /transmission {
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_set_header X-NginX-Proxy true;
        proxy_http_version 1.1;
        proxy_set_header Connection "";
        proxy_pass_header X-Transmission-Session-Id;
        add_header Front-End-Https on;

        location /transmission/rpc {
            proxy_pass http://transmission;
        }

        location /transmission/web/ {
            proxy_pass http://transmission;
        }

        location /transmission/upload {
            proxy_pass http://transmission;
        }

        location /transmission/web/style/ {
            alias /usr/share/transmission/web/style/;
        }

        location /transmission/web/javascript/ {
            alias /usr/share/transmission/web/javascript/;
        }

        location /transmission/web/images/ {
            alias /usr/share/transmission/web/images/;
        }

        location /transmission/ {
            return 301 https://$server_name/transmission/web;
        }
    }
}

初步读了一遍，配置文件中的/style/、/javascript/、/images/这三个location块应该是适用于Nginx与Transmission安装在同一台主机时使用的，于是我把它注释掉。

重启Nginx后使用一切正常。

我在想，就算Nginx与Transmission安装在同一台主机，如果不注释掉那三个location块，会不会也用不了自己安装的WebUI。
