title: REST Url for Lists
body: <p>Let's say I have a method that returns a list of customers and as input has a list of states and list of sizes, something like</p>
  
  <p>return customers where state in (NY, CA, TX) and size in (Small, Medium)</p>
  
  <p>What would the best RESTFul URL that I should use? The problem that it is a query and does not point to a specific 'resource'.  Here are some options that I am mulling over.</p>
  
  <ol>
  <li>somesite.com/customers?state=NY,CA,TX&amp;size=small,medium  (old style)</li>
  <li>somesite.com/customers/state/NY,CA,TX/size/small,medium</li>
  <li>somesite.com/customers/state=NY,CA,TX/size=small,medium</li>
  <li>somesite.com/customers/state(NY,CA,TX)/size(small,medium)</li>
  </ol>
