The information using the CURLOPT_VERBOSE is listed below.
The version we used is CURLv.7.16.2

======================================

It seems that the only different commnet(* part) CURL print is
"Connection #0 to host 192.168.10.143 left intact",
when comparing to those I can get the body correctly.
For example(success case),
======================================
< HTTP/1.1 200 OK

< Server: Boa/0.94.14rc21

* Closing connection #0
======================================

It's really appreciated for your reply.
