title: How Soap supports asynchronous call while Rest does not?
body: <p>I was going thru Soap vs Rest on net and found most of them says Soap supports asynchronous call while Rest does not but did not get any concrete example of that. Can anybody help me here? </p>
  
  <p>Here is one of the resources i was referring to</p>

  <p>As per my understanding both should be synchronous. In both cases client makes a call to web service either thru soap or rest, client waits till response comes back from service. So how come soap supports asynchronous behaviour while rest does not?</p>
