title: Difference jsonp and simple get request (cross domain)
body: <p>I have to send (and receive) certain data to a server using JQuery and JSON.
  Works so far, but not cross domain, and it has to be cross domain.</p>
  
  <p>I looked how to solve this and found JSONP. As far as I see, using JSONP I have to send the callback and the data using GET (JQuery allows to use "POST" as method, but when I inspect web traffic I see it is sending actually GET and everyting as parameter).</p>
  
  <p>JSONP also requires changes in the server, because they are expecting a POST request with JSON data, and they have to implement something to process the JSONP GET request.</p>
  
  <p>So I'm wondering what's the difference between this and sending the data as key value parameters in GET request?</p>
  
  <p>Is the difference the possibility to use a callback? Or what exactly?</p>
  
  <p>Sorry a bit lost... thanks in advance</p>
