HttpClient (Vert.x Core 3.4.2 API)

All Superinterfaces:

Measured
```
public interface HttpClient
extends Measured
```
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 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 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.

HttpClient redirectHandler(Function<HttpClientResponse,Future<HttpClientRequest>> handler)
```
    Set a redirect handler for the http client.
    The redirect handler is called when a 3xx response is received and the request is configured to follow redirects with HttpClientRequest.setFollowRedirects(boolean).
    The redirect handler is passed the HttpClientResponse, it can return an HttpClientRequest or null.
    - when null is returned, the original response is processed by the original request response handler
    - when a new Future<HttpClientRequest> is returned, the client will send this new request
    The handler must return a Future<HttpClientRequest> unsent so the client can further configure it and send it.
    Parameters:
    
    handler - the new redirect handler
    
    Returns:
    
    a reference to this, so the API can be used fluently
