title: Returning true/false in REST service?
body: <p>I'm designing a REST service and there's a need for a check to see if an address is correctly entered. What I'm thinking about is how you would design a REST interface for checking if an full street address is valid. </p>
  
  <p>I have this /address service and I could for example do a <code>POST /address/validation</code> which returns a xml/json true or false, but it seems quite un-REST-ful to me. </p>
  
  <p>Another way would be to do a <code>GET /address?street=xxx&amp;nr=xxx&amp;zipcode=xxx</code> (and a few more parameters) and return a 200 OK if correct or a 404 Not found if not correct, which may be more REST-ful?</p>
  
  <p>I started doing option 1) but the more I'm thinking about it, option 2) with the GET feels better... </p>
  
  <p>Ideas?</p>
