title: REST API using POST instead of GET
body: <p>Let's assume a service offers some funcionality that I can use like this:</p>
  
  <pre><code>GET /service/function?param1=value1&amp;param2=value2
  </code></pre>
  
  <p>Is it right to say that I can use it with a POST query?</p>
  
  <pre><code>POST /service/function { param1 : value1, param2 : value2 }
  </code></pre>
  
  <p>Are these two queries the same? Can I use the second variant in any case or the documentation should explicitly say that I can use both GET and POST queries?</p>
