I know, Jeff, that is simply my habit to say "expensive" while talking about
the overhead of any implementation : )

Joerg has said that callback is "cheap" and there is only one thread which
perform request sending and response receiving according to what
Dainel mention in another email

yes Jeff, I found this one while I debug my application, thanks : )

> Also note that the callback should return (size*nmemb) in order to
continue.

really? what happens if I don't do that?

haha, you are right !!
Finally I get it work with my multi-threaded application.
For my application, libcurl is much suitable than libwww which supports
pipeline though : )
