Hi all, I have problem with HTTP Server3 example, in connection::handle_write i have a dedline_timer with a async_wait. but before the handle_timed execute the connection_ptr goes out of scope, why? Appriciate any help. Christer The boost HTTP Server 3 in file connection.cpp in server.hpp boost::shared_ptr<connection> connection_ptr; server.cpp void server::handle_accept(const boost::system::error_code& e) { if (!e) { new_connection_->start(); new_connection_.reset(new connection(io_service_)); acceptor_.async_accept(new_connection_->socket(), boost::bind(&server::handle_accept, this, boost::asio::placeholders::error)); } } in connection.cpp void connection::handle_write(const boost::system::error_code& e) { if (!e) { const boost::shared_ptrboost::asio::deadline_timer t(new boost::asio::deadline_timer(*io_service_, boost::posix_time::seconds(15))); } } void connection::handle_timed( const boost::system::error_code& ec, const boost::shared_ptrboost::asio::deadline_timer t) { syslog(LOG_INFO, "handle_timed: %s", ec.message().c_str()); }
