Hello,

Thanks for your response but they won't working.

Here is my conf :

nginx.conf :
user www-data;
worker_processes 1;

error_log /var/log/nginx/error.log;
pid /var/run/nginx.pid;

events {
worker_connections 1024;
# multi_accept on;
}

http {
include /etc/nginx/mime.types;

access_log /var/log/nginx/access.log;

sendfile on;
#tcp_nopush on;

#keepalive_timeout 0;
keepalive_timeout 65;
tcp_nodelay on;

gzip on;
gzip_disable "MSIE [1-6]\.(?!.*SV1)";

include /etc/nginx/conf.d/*.conf;
include /etc/nginx/sites-enabled/*;
}

my vhost :
server {
listen [::]:80;

server_name proxy.com *.proxy.com;

access_log /var/log/nginx/proxy_.access.log;

error_page 404 = /404.htm;

location /404.htm {
root /var/www;
}

location / {
proxy_set_header X-Forwarded-Host $host;
proxy_set_header X-Forwarded-Server $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;


if ($host ~* ^proxy\.com$) {
proxy_pass http://mydomain.com;
}

if ($host ~* ^www\.proxy\.com$) {
proxy_pass http://www.mydomain.com;
}

if ($host ~* ^subdomain\.proxy\.com$) {
proxy_pass http://subdomain.mydomain.com;
}

proxy_redirect http://proxy.com/test http://proxy.com/test/;
}
}

and my proxy.conf file :
proxy_redirect off;
proxy_intercept_errors on;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
client_max_body_size 10m;
