title: How to send a resource collection using Restangular?
body: <p>Let's say I want to send a <code>DELETE</code> request to a resource like <code>/products</code> and I want to delete multiple products.</p>
  
  <p>The whole request would be to the following URI: <code>/products/ids=1&amp;ids=2&amp;ids=3</code></p>
  
  <p>How can I issue a request like the above one using Restangular? </p>
  
  <p>For now, the issue is that <code>customDELETE</code> receives query string params using an object. Hence, it can't define the same parameter more than once...</p>
