title: REST API: GET request with body
body: <p>I want to implement a REST API and need a body on my GET requests. (Like discussed here: <a href="https://stackoverflow.com/questions/978061/http-get-with-request-body">HTTP GET with request body</a>)</p>
  
  <p>Are there http clients which are not able to send a body with a GET request? Fiddler is able to do it, although the message box is red.</p>
