title: Restbed: issue when i try to make a requst containing JSON parameter
body: <p>Im fairly new to REST and i have tried to run basic tutorial code of Restbed that goes as follows:</p>
  
  <pre><code>#include &lt;memory&gt;
  #include &lt;cstdlib&gt;
  #include &lt;restbed&gt;
  
  using namespace std;
  using namespace restbed;
  
  void get_method_handler( const shared_ptr&lt; Session &gt; session )
  {
      session-&gt;close( OK, "Hello, World!", { { "Content-Length", "13" }, { "Connection", "close" } } );
  }
  
  int main( const int, const char** )
  {
      auto resource = make_shared&lt; Resource &gt;( );
      resource-&gt;set_path( "/resource" );
      resource-&gt;set_method_handler( "GET", get_method_handler );
  
      //auto ssl_settings = make_shared&lt; SSLSettings &gt;( );
      //ssl_settings-&gt;set_http_disabled( true );
      //ssl_settings-&gt;set_private_key( Uri( "file:///tmp/server.key" ) );
      //ssl_settings-&gt;set_certificate( Uri( "file:///tmp/server.crt" ) );
      //ssl_settings-&gt;set_temporary_diffie_hellman( Uri( "file:///tmp/dh768.pem" ) );
  
      auto settings = make_shared&lt; Settings &gt;( );
      //settings-&gt;set_ssl_settings( ssl_settings );
  
      Service service;
      service.publish( resource );
      service.start( settings );
  
      return EXIT_SUCCESS;
  }
  </code></pre>
  
  <p>Please note: the SSL init is commented out.
  When i make just a basic request (<a href="http://localhost/resource" rel="nofollow noreferrer">http://localhost/resource</a>) everything is fine.
  With just a bit more complex request containing a parameter (<a href="http://localhost/resource?request=test" rel="nofollow noreferrer">http://localhost/resource?request=test</a>) its still working as intended. When i try to pass in JSON object (<a href="http://localhost/resource?request=" rel="nofollow noreferrer">http://localhost/resource?request=</a>{}) i get an error stating "Your client has issued a malformed or illegal request status line. That’s all we know.". I can get over this issue by running this command from Postman rather than browser but even then as soon as i change the command to <a href="http://localhost/resource?request=" rel="nofollow noreferrer">http://localhost/resource?request=</a>{"test"=[]} it ends up with the same error again.</p>
  
  <p>Can anyone shed a bit of light on what issue im looking at?
  Im running 64 bit windows 10, compiling the code in Visual Studio 2017.</p>
  
  <p>Thank you in advance</p>
