I also didn't see what libcurl version you're using.

It *blocks* ? Sorry but I don't see how that can happen. I assume you mean
that there's a handle in there that doesn't seem to complete?

So you never get any event for the new socket that curl created for the TCP
connection? Then libcurl won't know the connect failed! Or am I missing
something?

A slow server is not a problem, it is perfectly permissable by both TCP and
HTTP.

I don't understand. Who is 'I' here that write to the socket? Aren't you using
libcurl so it will write to the socket by itself? How does asio affect that?
And libcurl won't write to the socket until after it has connected anyway!
