ic-push-url not working return

Related to https://github.com/LeadDyno/intercooler-js/issues/77#issuecomment-174027468
Can You show me example of X-IC-PushURL ? @carsongross
I can't make it work in client-side script only. My backend dev w
on't hear about return special http headers.

For me if some field is sent by GET method it have to appear in url adress like in simple
```` url..

There is code example of my project (new lines only for readability):
```

{% for item in arr %}

{{item.nazwa}}

{% endfor %}

```
or
```

//
//
//
//
//

{% for item in arr %}

{{item.nazwa}}

{% endfor %}

```

No file or test is named. Reproduce the supplied HTML form with ic-push-url and compare its client-side behavior with the linked discussion of X-IC-PushURL; done means the expected GET parameters and browser URL behavior are verified or documented with a working example.
