| /** |
| * Jetty Client : Implementation and Core Classes |
| * |
| * This package provides APIs, utility classes and an implementation of an asynchronous HTTP client. |
| * <p /> |
| * The core class is {@link org.eclipse.jetty.client.api.HttpClient}, which acts as a central configuration object (for example |
| * for {@link org.eclipse.jetty.client.api.HttpClient#setIdleTimeout(long) idle timeouts}, {@link org.eclipse.jetty.client.api.HttpClient#setMaxConnectionsPerDestination(int) |
| * max connections per destination}, etc.) and as a factory for {@link Request} objects. |
| * <p /> |
| * The HTTP protocol is based on the request/response paradigm, a unit that in this implementation is called |
| * <em>exchange</em> and is represented by {@link org.eclipse.jetty.client.api.HttpExchange}. |
| * An initial request may trigger a sequence of exchanges with one or more servers, called a <em>conversation</em> |
| * and represented by {@link org.eclipse.jetty.client.api.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. |
| * <p /> |
| * {@link org.eclipse.jetty.client.api.HttpClient} holds a number of {@link org.eclipse.jetty.client.api.HttpDestination destinations}, which in turn hold a number of |
| * pooled {@link org.eclipse.jetty.client.api.HttpConnection connections}. |
| * <p /> |
| * 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. |
| * Conversations may span multiple connections on different destinations, and therefore are maintained at the |
| * {@link org.eclipse.jetty.client.api.HttpClient} level. |
| * <p /> |
| * Applications may decide to send the request and wait for the response in a blocking way, using |
| * {@link org.eclipse.jetty.client.api.Request#send()}. |
| * Alternatively, application may ask to be notified of response events asynchronously, using |
| * {@link org.eclipse.jetty.client.api.Request#send(Response.Listener)}. |
