### Example Custom Template
Use case: add an `X-Served-By` header to requests
```go
server {
listen [::]:{{ .NGINX_PORT }};
listen {{ .NGINX_PORT }};
server_name {{ .NOSSL_SERVER_NAME }};
access_log /var/log/nginx/{{ .APP }}-access.log;
error_log /var/log/nginx/{{ .APP }}-error.log;
# set a custom header for requests
add_header X-Served-By www-ec2-01;

proxy_set_header X-Request-Start $msec;
}
include {{ .DOKKU_ROOT }}/{{ .APP }}/nginx.conf.d/*.conf;
}
upstream {{ .APP }} {
{{ range .DOKKU_APP_LISTENERS | split " " }}
server {{ . }};
{{ end }}
}
```
### Example HTTP to HTTPS Custom Template
Use case: a simple dockerfile app that includes `EXPOSE 80`
```go
server {
listen [::]:80;
listen 80;
server_name {{ .NOSSL_SERVER_NAME }};
access_log /var/log/nginx/{{ .APP }}-access.log;
error_log /var/log/nginx/{{ .APP }}-error.log;
return 301 https://$host:443$request_uri;
}
server {
listen [::]:{{ $listen_port }} ssl {{ if eq $.HTTP2_SUPPORTED "true" }}http2{{ else if eq $.SPDY_SUPPORTED "true" }}spdy{{ end }};
listen {{ $listen_port }} ssl {{ if eq $.HTTP2_SUPPORTED "true" }}http2{{ else if eq $.SPDY_SUPPORTED "true" }}spdy{{ end }};
{{ if .NOSSL_SERVER_NAME }}server_name {{ .NOSSL_SERVER_NAME }}; {{ end }}
{{ if .SSL_SERVER_NAME }}server_name {{ .SSL_SERVER_NAME }}; {{ end }}
access_log /var/log/nginx/{{ .APP }}-access.log;
error_log /var/log/nginx/{{ .APP }}-error.log;
ssl_certificate {{ .APP_SSL_PATH }}/server.crt;
ssl_certificate_key {{ .APP_SSL_PATH }}/server.key;

location / {
proxy_pass http://{{ .APP }};
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header Host $http_host;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header X-Forwarded-Port $server_port;
proxy_set_header X-Request-Start $msec;
}
include {{ .DOKKU_ROOT }}/{{ .APP }}/nginx.conf.d/*.conf;
}
upstream {{ .APP }} {
{{ range .DOKKU_APP_LISTENERS | split " " }}
server {{ . }};
{{ end }}
}
```
### Example using new proxy port mapping
```go
{{ range $port_map := .PROXY_PORT_MAP | split " " }}
{{ $port_map_list := $port_map | split ":" }}
{{ $scheme := index $port_map_list 0 }}
{{ $listen_port := index $port_map_list 1 }}
{{ $upstream_port := index $port_map_list 2 }}
server {
listen [::]:{{ $listen_port }};
listen {{ $listen_port }};
server_name {{ $.NOSSL_SERVER_NAME }};
access_log /var/log/nginx/{{ $.APP }}-access.log;
error_log /var/log/nginx/{{ $.APP }}-error.log;
location / {

gzip_vary on;
gzip_comp_level 6;
proxy_pass http://{{ $.APP }}-{{ $upstream_port }};
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header Host $http_host;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header X-Forwarded-Port $server_port;
proxy_set_header X-Request-Start $msec;
}
include {{ $.DOKKU_ROOT }}/{{ $.APP }}/nginx.conf.d/*.conf;
}
{{ range $upstream_port := $.PROXY_UPSTREAM_PORTS | split " " }}
upstream {{ $.APP }}-{{ $upstream_port }} {

### Customizing via configuration files included by the default templates
The default nginx.conf template will include everything from your apps `nginx.conf.d/` subdirectory in the main `server {}` block (see above):
