On the Bleeding Edge of Web to Host
Thin Client Approaches
Web Server On Mainframe—Browser connects directly to the mainframe or midrange via HTTP/HTML and does not employ a gateway.
HTML Gateway To Mainframe—Browser to gateway which connects directly to mainframe via SNA converts SNA data stream on the fly to HTML.
Hybrid HTML Gateway To Mainframe —Gateway connects to mainframe via SNA and browser connects to gateway via Java for persistence.
Java Applet Or Application—Browser connects directly to mainframe or gateway via Java after being requested from the Web to Host server.
Active X Applet—Browser connects to mainframe or gateway via Active X applet.
Proprietary middleware — spawns Java applet upon request from the desktop.
