Regarding HttpClient 4.0.

[Techie India]

 Hi,

I want to know what are the major difference HttpClient 3.0 and  HttpClient
4.0, what are major issues which HttpClient 4.0 will adress which were
missing in HttpClient 3.0.


Is there a nio and classic I/O model  for HttpClient 4.0 as well, like in
httpCore?

Thanks
