you have to manually change the url above to:<br>
/search?foo[]=1&foo[]=2&foo[]=3<br><br>

<b>OUTPUT</b>
foo array contains: {{foo}}<br><br>
Click one to remove from array:<br>
(then note strange QP format change on url - how can ember retain the parameter-array format?)<br><br>

{{#each foo as |f|}}
delete <a href="#" {{action "removeItem" f}}>{{f}}</a><br>
{{/each}}
{{outlet}}

{{link-to 'Click Here' 'search' }}

<h1>Welcome to {{appName}}</h1>
<br>
<br>
{{outlet}}
