What version of cpp-netlib are you using? There was a discussion about this
a month and a half ago and the decision was to define a macro
BOOST_NETWORK_ENABLE_HTTPS in order to explicitly opt-in to using SSL.
However, this has not yet been implemented. It is not possible to compile
the HTTP client without SSL in the current release (0.6).

The internal details can be quite obscure, but it is a stated goal that
using the library should not be hard to do. Admittedly, the documentation
is still incomplete but I am making an effort to make it more accessible.
If you have anything specific you want addressed, please let me know and I
will try to deal with it.

I think you're right. The HTTP server provided is very simple, but
eventually cpp-netlib ought to provide the building blocks for more complex
servers. I know Dean has more ideas on this, he could let you know more
about his plans.

As Dean already mentioned, he is working on an asynchronous HTTP client so I
will leave it to him to respond more fully to this.

Yes, but as with (2) it's simply a matter of implementing it.
