Hey, I have to point out two mistakes:
<title>Chat Room</title>
In the_ticker.html

Also there is the jQuery script in the_ticker.html that is not needed since 
you're using plain JS for this example.

You're welcome, I'm glad I helped.

Why did you write

void main(std::string /*url*/)

and not

void main(std::string /url)

?

Hi, I have a question about:

context->async_on_peer_reset([=](){
         this->waiters_.erase(context);
});

Why are you catching things in the labda by value, not by reference?

Because I don't use URL dispatching so I don't need url variable,
and this prevents warning about unused parameter with -Wall -Wextra

Because I need to variables:

- "this" witch technically may be 
  captured by reference as well, but not really needed.
- "context" - the shared_ptr on the http::context that
  would go out of scope when the callback is called.

Yeah, I thought about "context" going out of scope just after sending the email.

Thanks!
