System and method of automatically transforming instant message transmission modes on internet

A system of automatic transforming instant message transmission modes on Internet, said system comprises:

• at least two clients, wherein said client includes a computer system, said computer system comprises a web browser, a first packet-processing program, a network configuration processing program for detecting and identifying a network auto-configuration, a proxy configuration processing program for detecting and identifying a proxy configuration, a connection time-out program, and a Java applet identification program for determining if said client be allowable of downloading and installing a Java applet, and said web browser includes a network auto-configuration and a proxy configuration;
• and
• a server, wherein said server comprises a second packet-processing program for processing a plurality of transmitting packets between said server and said client, a conference management program for opening or closing a network conference and for managing the login and logout of said client, a message broadcast program for transmitting at least a message to said client and for broadcasting said messages to a plurality of clients participating in said network conference, a mode 1 processing program for processing network connection mechanism of the mode 1 and decoding a plurality of packets of the mode 1, a mode 2 processing program for processing network connection mechanism of the mode 2 and decoding a plurality of packets of the mode 2, a mode 3 processing program for processing network connection mechanism of the mode 3 and decoding a plurality of packets of the mode 3, and a mode 4 processing program for processing network connection mechanism of the mode 4 and decoding a plurality of packets of the mode 4;
• wherein said mode 1 means a connection that the client connects to the server directly through any allowable socket, said mode 2 means a connection that the client connects to the server across proxy servers and firewalls supporting persistent HTTP 1.1 connection, said mode 3 means a connection that the client connects to the server across proxy servers and firewalls supporting non-persistent HTTP 1.0 connection, and said mode 4 means a connection that a web-based instant interactive message application is applied.
