30. Log_format Main ' $remote _addr-$remote _user [$time _local] "$request" '
32. ' $status $body _bytes_sent ' $http _referer '

48. server {
50. Resolver 10.57.220.2;
52. Listen 82;
54. Access_log Logs/host.access.log Main;
58. Location/{
60. Proxy_pass http://$http _host$request_uri;
62. }
68. }
