# URL

## Whitelist an IP in NGINX for a URL

If you want to whitelist an IP for just one URL (e.g. /accounts/login) then add the *allow* directive below in the *location* block of that URL.

```
location /accounts/login {
   allow 45.43.23.21;
   deny all;
}
```

## Restart NGINX

Run the following command to check the syntax of your updated config file.

```
sudo nginx -t
```

If there are no errors, run the following command to restart the NGINX server.

```
sudo systemctl restart nginx
```
