The HttpRequest entity has the following attributes:

Content (inherited from HttpMessage) String empty The body of the request.

You can retrieve the request headers via the HttpHeaders association.

The HttpResponse entity has the following attributes:

Attribute Type Default Value Description
HttpVersion (inherited from HttpMessage) String HTTP/1.1 The protocol version. You can almost always ignore this value.
StatusCode Integer 200 The HTTP status code returned by the server.
