4. I was using Pusher on some projects behind a firewall;

# Features

  key_file: "key.pem"
  cert_file: "cert.pem"
apps:
  - name: "Sample Application"
    enabled: true
    only_ssl: false

```

## Libraries

### Client javascript library

```javascript
let pusher = new Pusher(APP_KEY, {
  wsHost: 'localhost',
  wsPort: 8080,
  wssPort: 4433,    // Required if encrypted is true
  encrypted: false, // Optional. the application must use only SSL connections
  enabledTransports: ["ws", "flash"],
  disabledTransports: ["flash"]
});
```

### Client server libraries

Ruby

```ruby
Pusher.host = 'localhost'
Pusher.port = 8080
```

PHP

```php
$pusher = new Pusher(APP_KEY, APP_SECRET, APP_ID, DEBUG, "http://localhost", "8080");
```

Go

```go
package main

import "github.com/pusher/pusher-http-go"

func main() {
	client := pusher.Client{
        AppId:  "APP_ID",
        Key:    "APP_KEY",
        Secret: "APP_SECRET",
        Host:   ":8080",
    }
	
	// use the client
}
```

NodeJS

```javascript
let pusher = new Pusher({
  appId: APP_ID,
  key: APP_KEY,
  secret: APP_SECRET
  domain: 'localhost',
  port: 80
});
