Nginx常见问题解决

1、nginx 或者tomcat 下 X-Content-Type-Options、X-XSS-Protection、Content-Security-Pol安全配置

add_header X-Frame-Options "SAMEORIGIN"; add_header X-XSS-Protection "1; mode=block"; add_header X-Content-Type-Options "nosniff";

 

2、nginx: [emerg] unknown "connection_upgrade" variable解决与思考

http {     map $http_upgrade $connection_upgrade {     default upgrade;     ''      close;    }      server {         location / {                     #…                 proxy_set_header Upgrade $http_upgrade;                 proxy_set_header Connection $connection_upgrade;             }         } }
