## Apache

Apache and mod_proxy should not decode/encode slashes and leave them as they are:

````
<VirtualHost *:80>
  AllowEncodedSlashes NoDecode
  ProxyPass /npm http://127.0.0.1:4873 nocanon
  ProxyPassReverse /npm http://127.0.0.1:4873
</VirtualHost>
````

### Configuration with SSL

config.yaml

```yaml
url_prefix: https://npm.your.domain.com
```

Apache virtual server configuration

````
    apacheconfig
    <IfModule mod_ssl.c>
    <VirtualHost *:443>
        ServerName npm.your.domain.com
        SSLEngine on
        SSLCertificateFile      /etc/letsencrypt/live/npm.your.domain.com/fullchain.pem
        SSLCertificateKeyFile   /etc/letsencrypt/live/npm.your.domain.com/privkey.pem
        SSLProxyEngine          On
        ProxyRequests           Off
        ProxyPreserveHost       On
        AllowEncodedSlashes     NoDecode
        ProxyPass               /       http://127.0.0.1:4873 nocanon
        ProxyPassReverse        /       http://127.0.0.1:4873
    </VirtualHost>
    </IfModule>
````

## Nginx


````
server {
  listen 80 default_server;
  location / {
    proxy_pass              http://127.0.0.1:4873/;
    proxy_set_header        Host $host;
  }
}
````

## Run behind reverse proxy with different domain and port

If you run verdaccio behind reverse proxy, you may noticed all resource file served as relaticve path, like `http://127.0.0.1:4873/-/static`

To resolve this issue, you should send real domain and port to verdaccio with `Host` heade

Nginx configure should look like this:

```nginx
location / {
    proxy_pass http://127.0.0.1:4873/;
    proxy_set_header Host            $host:$server_port;
    proxy_set_header X-Forwarded-For $remote_addr;
    proxy_set_header X-Forwarded-Proto $scheme;
}
```
For this case, `url_prefix` should NOT set in verdaccio config

---
or a sub-directory installation:

```nginx
location ~ ^/verdaccio/(.*)$ {
    proxy_pass http://127.0.0.1:4873/$1;
    proxy_set_header Host            $host:$server_port;
    proxy_set_header X-Forwarded-For $remote_addr;
    proxy_set_header X-Forwarded-Proto $scheme;
}
```
For this case, `url_prefix` should set to `/verdaccio/`

> Note: There is a Slash after install path (`https://your-domain:port/vardaccio/`)!
