[SR-Users] http_async_client

[Alex Balashov]

It will not go back to request_route; you'll have to make peace with that.

Most things are valid in the continued route. A few will doubtless 
exhibit quirky behaviour as the state doesn't make it across properly 
from the original requet_route. I haven't been adversely impacted by 
this in my extensive use of http_async_client(), however.
