The following changes have been made since Alpha 3:
* Changed HttpConnection to use socket timeout instead of busy waiting while expecting input.
* Added a getResponseContentLength() method to HttpMethod.
* Changed HttpClient to accept correctly encoded URLs instead of attempting to encode them within HttpClient.
* 'Expect: 100-continue' logic factored out into an abstract ExpectContinueMethod class
* 'Expect: 100-Continue' handshake disabled per default, as it may not work
properly with older HTTP/1.0 servers or proxies.
* Reengineered authentication code. This includes a fix for
HttpClient continually attempting to authenticate to digest realms and
provides for better future extensibility.
* Authenticator class deprecated
* Improved user documentation and example code.
* Added ability to differentiate between different hosts using the same realm names.
* Added support for specifying a virtual host name to use.
* Fixed problem with half-closed connections causing a
HttpRecoverableException to be thrown when HttpClient attempts to read
from a socket.
* Improved reliability with the HEAD method and servers that incorrectly include a response body.
* Improved support for connection keep-alive when communicating via a proxy
* Added an override of HttpClient.executeMethod that lets the caller specify an HttpState object.
* HttpConnectionManager is now a property of the HttpClient class, not of the HttpState class
* Added ability to specify the local address that HttpClient should create connections from.
