public class HttpClientRequest extends Object implements WriteStream<Buffer>, ReadStream<HttpClientResponse>
Instances are created by an HttpClient instance, via one of the methods corresponding to the
specific HTTP methods, or the generic request methods. On creation the request will not have been written to the
wire.
Once a request has been obtained, headers can be set on it, and data can be written to its body if required. Once
you are ready to send the request, one of the end(java.lang.String) methods should be called.
Nothing is actually sent until the request has been internally assigned an HTTP connection.
The HttpClient instance will return an instance of this class immediately, even if there are no HTTP
connections available in the pool. Any requests sent before a connection is assigned will be queued
internally and actually sent when an HTTP connection becomes available from the pool.
The headers of the request are queued for writing either when the end(java.lang.String) method is called, or, when the first
part of the body is written, whichever occurs first.
This class supports both chunked and non-chunked HTTP.
It implements WriteStream so it can be used with
Pump to pump data with flow control.
An example of using this class is as follows:

if there is more than maxSize items in the write queue. This is used as an indicator by classes such as
Pump to provide flow control.

You can then continue to write data to the request body and later end it. This is normally used in conjunction with
the sendHead() method to force the request header to be written before the request has ended.
