public interface NHttpConnection
extends org.apache.http.HttpConnection, IOControl

Abstract non-blocking HTTP connection interface. Each connection contains an HTTP execution context, which can be used to maintain a processing state, as well as the actual HttpRequest and HttpResponse that are being transmitted over this connection. Both the request and the response objects can be null if there is no incoming or outgoing message currently being transferred.

Please note non-blocking HTTP connections are stateful and not thread safe. Input / output operations on non-blocking HTTP connections should be restricted to the dispatch events triggered by the I/O event dispatch thread. However, the IOControl interface is fully threading safe and can be manipulated from any thread.
