title: What is the best method for accessing a resource which is non-deterministic?
body: <p>Lets say I am building a web service that is returning a random number?</p>
  
  <p>Real world example: <a href="http://www.random.org/integers/?num=10&amp;min=1&amp;max=6&amp;col=1&amp;base=10&amp;format=plain&amp;rnd=new" rel="nofollow">http://www.random.org/integers/?num=10&amp;min=1&amp;max=6&amp;col=1&amp;base=10&amp;format=plain&amp;rnd=new</a></p>
  
  <p>random.org does this via GET method, which is not RESTful I think. Specs are saying that GET method should be idempotent.</p>
  
  <p>What method would you suggest and what would your URL be?</p>
