[Application design] How to delete instance of class waiting for asynchronous IO.

Boost

Hello,

At the moment I have a little design issue. I created proxy server for my application, but I'm having trouble to delete sessions. (using boost::asio)

I obviously have two sockets. One connected from proxy to client and one connected from proxy to server. I use async operations to recv/send data on those sockets. However when error occurs and the socket is closed, I want to delete that session. However if I delete the session, the handler of the other socket is called too and the delete is called twice (which leads to crash of-course).

Any ideas how to fix that are welcome.

Ex.:

//m_socket1 handler:
void CSomeSession::Handler_SendToClient( const boost::system::error_code& error)
{
	if( error)
	{
		std::cout << error.message() << std::endl;		
		delete this;
	}
}

//m_socket2 handler:
void CSomeSession::Handler_SendToServer( const boost::system::error_code& error)
{
	if( error)
	{
		std::cout << error.message() << std::endl;		
		delete this;
	}
}

Same goes for recv.

Thank you for your help.
