public class EmptyContent implements HttpContent
Empty HTTP content of length zero just to force HttpRequest#execute() to add the header
Content-Length: 0
.
Note that there is no Content-Length
header if the HTTP request content is
null
. However, when making a request like PUT or POST without a Content-Length
header,
some servers may respond with a 411 Length Required
error. Specifying the
Content-Length: 0
header may work around that problem.

writeTo(OutputStream out)
