before the connect timeout.
The changes to fix this issue uncovered problems in the HttpSender
state machine.
In particular, the SenderState is now defining more states that
depend on deferred content, and on handling of 100 Continue responses.
The refactoring also highlighted the fact that there was no need to
keep HttpConversation objects in a Map in HttpClient: they are now
only referenced by the HttpRequest.
With this change, Request.getConversationID() has been deprecated.
Also fixed a number of tests to make them more reliable.
Big refactoring to allow for additional proxy schemes that work at a
lower level than HTTP.
Introduced client-side ConnectionFactory, and binding that to a
HttpDestination, so that connections to that destination will use the
same ConnectionFactory.
The destination's ConnectionFactory is now initialized from the proxy
configuration and the transport, which is now itself a
ConnectionFactory.
The proxy configuration has also changed becoming polymorphic by
introducing a new ProxyConfiguration.Proxy abstract class,
which is implemented as HTTPProxy and can be implemented in future as
SOCKS4Proxy (and possibly others).
Merge of the branch 'http_client_transport' is now complete,
and the implementation is sound for the HTTP transport.
A basic implementation for the SPDY transport exists, but needs
improvements.
