### Proxy URL
Defining the proxy URL will prefix all snippet requests with it. This allows you to use a script to access the
snippet files.

```js
{
sampler : {
proxyURL: 'task.php?file='
}
}
```

If you're trying to load a language that your webserver understands (for example PHP) you
can create a proxy script that passes the source of the file trough. Be careful to
limit the script to the source files you would like to deliver.
