Represents a server-side HTTP request.

Instances are created for each request and passed to the user via a handler.
 Each instance of this class is associated with a corresponding HttpServerResponse instance via response.
 It implements ReadStream so it can be used with Pump to pump data with flow control. 

 NOTE: This class has been automatically generated from the original non RX-ified interface using Vert.x codegen. /**

Get a net socket for the underlying connection of this request.

This method must be called before the server response is ended.

With CONNECT requests, a 200 response is sent with no content-length header set
before returning the socket.

For other HTTP/1 requests once you have called this method, you must handle writing to the connection yourself using
the net socket, the server request instance will no longer be usable as normal. USE THIS WITH CAUTION! Writing to the socket directly if you don't know what you're
doing can easily break the HTTP protocol.

like in the CONNECT case above.
