Package org.eclipse.jetty.client Description

This package provides APIs, utility classes and implementation class of an asynchronous HTTP client

The core class is HttpClient, which acts as a central configuration object (for example for idle timeouts, max connections per domain, etc.) and as a factory for Request objects.

The HTTP protocol is based on the request/response paradigm, a unit that in this implementation is called exchange and is represented by HttpExchange. An initial request may trigger a sequence of exchanges with one or more servers, called a conversation and represented by HttpConversation. A typical example of a conversation is a redirect, where upon a request for a resource URI, the server replies with a redirect (for example with the 303 status code) to another URI. This conversation is made of a first exchange made of the original request and its 303 response, and of a second exchange made of the request for the new URI and its 200 response.

HttpClient holds a number of destinations, which in turn hold a number of pooled connections.

When a request is sent, its exchange is associated to a connection, either taken from an idle queue or created anew, and when both the request and response are completed, the exchange is disassociated from the connection. A conversation may span multiple connections on different destinations, and therefore are maintained at the HttpClient level.

Applications may decide to send the request and wait for the response in a blocking way, using Request#send(). Alternatively, application may ask to be notified of response events asynchronously, using Request#send(Response.Listener).
