nginx proxy_pass

　　

 

1. proxy_pass可以实现URL路径的替换,跟alias很像
   proxy_pass,不带 "/" 时,只代理域名,URI(包括query_string)不改变,URI直接附加到proxy_pass指定的域名
   proxy_pass,后跟 "/" 时,会把location匹配的部分完全删除后,附加于proxy_pass后

           proxy_pass http://rear:8080;
       }
   }
   
   http://domain/vod/b.html => http://rear:8080/vod./b.html
   
   server {
       location /vod {
           proxy_pass http://rear:8080/;
       }
   }

           proxy_pass http://rear:8080/edu;
       }
   }
   
   http://domain/vod/b.html => http:rear:8080/edu/b.html
   
   server {
       location /vod/ {
           proxy_pass http://rear:8080/edu;
       }
   }
   
   http://domain/vod/b.html => http:rear:8080/edub.html  # usually a mistake
