100 concurrent connections is easy to handle. But not with the current
implementation of the HTTP client.

You cannot do that yet now.

I might implement a wrapper or a simple check on the response objects
to see whether the body part is done. It should be trivial to do but
I'm concentrating on the server side.

Maybe others on the list might want to implement this for the
asynchronous basic_response<Tag> overload where Tag is asynchronous?
*hint*. :)

These are not possible yet. As I've said earlier, this will be made
possible in a later release, potentially 0.9, which will come after
0.8 (scheduled for release next week).
