hello,I used the hello_word_client to communicate with the hello_world_async_server_with_work_queue,but can't get response,the errors are:

1.C:\Users\Administrator\Desktop>hello_world_client.exe http://127.0.0.1:8000
[DEBUG C:\boost_1_55_0\boost/network/protocol/http/client/connection/async_proto
col_handler.hpp:119]: [parser:1] buffer contents: "Hello, 127.0.0.1:2460:52685!"
Invalid Version Part.

2.I use the client to post a string to server .I find that the the body of request that the server recieved is empty,
what' s matter?
ps： if I use the hello_world_server it is OK.I use the vs2013+cpp-netlib 1.1+boost1.55
