Abstract
An asynchronous hypertext messaging system and method are disclosed. The system and method use existing hypertext transfer protocols and is capable of transmitting real-time asynchronous data between server and client regardless of firewalls or proxy servers implemented at the client or the server. In a communication system comprising a client and server interconnected by an internet, initial authentication is performed initially between the server and the client. A secure log in is performed by the client with the server in conjunction with a possible java applet download. The communication server then initiates a multiplexed virtual connection between the server and the client and transmission of asynchronous real-time data can occur over the virtual connection. The virtual connection is periodically refreshed by a request issued from the java applet.
