When I reviewed your code I felt most of those uses were easily 
replaced, and moreover doing so would improve the quality of your 
code. I hope you don't mind me saying, but I felt some of your 
choices were you experimenting with fun new tools rather than what 
was the best solution (which is often the easiest and simplest 
solution).

I'll wait to your community review to go into more detail. I didn't 
examine Http in too much depth yet.

As I have mentioned to you before, you can ask ASIO to tell you which 
error code system it uses, moreover ASIO itself can be configured 
with more than one error code implementation, so you need to pick up 
whatever it's been configured with. I'd also support standalone ASIO 
if I were you, and then you'll be ready for the Networking TS. You 
might consider replicating what AFIO does to use ASIO via APIBind, 
then you can support Boost.ASIO and the Networking TS with no extra 
work.

Boost has an excellent C++ 11 enum emulation based on macros. And 
yes, I agree Http doesn't use a ton of 11 yet. ASIO in many ways 
forces you to use idioms which are very fast on 03, so the need for 
11 isn't as acute.
