/**
* An asynchronous HTTP client.
*
* It allows you to make requests to HTTP servers, and a single client can make requests to any server.
*
* It also allows you to open WebSockets to servers.
*
* The client can also pool HTTP connections.
*
* For pooling to occur, keep-alive must be true on the {@link io.vertx.core.http.HttpClientOptions} (default is true).
* In this case connections will be pooled and re-used if there are pending HTTP requests waiting to get a connection,
* otherwise they will be closed.
*
* This gives the benefits of keep alive when the client is loaded but means we don't keep connections hanging around
* unnecessarily when there would be no benefits anyway.
*
* The client also supports pipe-lining of requests. Pipe-lining means another request is sent on the same connection
* before the response from the preceding one has returned. Pipe-lining is not appropriate for all requests.
*
* To enable pipe-lining, it must be enabled on the {@link io.vertx.core.http.HttpClientOptions} (default is false).
*
* When pipe-lining is enabled the connection will be automatically closed when all in-flight responses have returned
* and there are no outstanding pending requests to write.
*
* The client is designed to be reused between requests.
*
*
* NOTE: This class has been automatically generated from the {@link io.vertx.core.http.HttpClient original} non RX-ified interface using Vert.x codegen.
