This is a java wrapper around the old commons-http-client.3.1 HTTP client which not developed anymore.
The wrapper is using the new HttpClient 4.x and keeps binary compatibility.
The intention for developing this wrapper was using Axis 2 for accessing a Microsoft Exchange 2010 server which requires a NTLM2 authentication.
Not all methods are implemented, but it works for me.
Just remove the old commons-httpclient-3.1.jar and add http-client-3-wrapper to your project.
