A bidirectional communication method allowing real-time information sharing among clients on an Intranet through a server on the Internet in disclosed. After establishing two connections between the server and the client through an HTTP proxy, one of the two connections is set to a downstream connection using GET method of HTTP to allow real-time data transfer from the server to the client. Thereafter, the other of the two connections is set to an upstream connection using POST method of HTTP to allow real-time data transfer from the client to the server. After having set the upstream connection and the downstream connection, data cells are transferred between the server and the client through the upstream connection and the downstream connection.
