The failed job seems not a problem of this PR.

session_data.event_handle;
{
std::lock_guard<std::recursive_mutex> guard{session_manager_lock_};
static_cast<ResponseHandler *>(handle.get())->Bind(this, *session);

No, it's not necessary, but I think ResponseHandler::Bind and inserting element into running_sessions_ below should work together logically.


HttpSessionData &store_session_data = running_sessions_[key];
store_session_data = std::move(session_data);
HttpSessionData &store_session_data = running_sessions_[session.get()];

Just curious , why can't we just use session_data.session.get() instead of session.get() for indexing here?
