Nginx can be easily configured as a reverse proxy server:
server {
listen;
server_name localhost;
Location/{
Proxy_pass http://x.x.x.x:9500;
Proxy_set_header Host $host:
Proxy_set_header x-real-ip $remote _addr;
Proxy_set_header x-forwarded-for $proxy _add_x_forwarded_for;
Proxy_set_header Via "Nginx";
