Use an HTML Display session
BlueZone Access Server for 5250, 3270 and VT100 delivers zero-foot print, browser and OS independent HTML display over the Internet. From one instance of a standard Web browser, users can request one HTML Display session per emulation type at the same time. Each session opens as a separate window.
To open multiple HTML display sessions, you must start each one from a different instance of the browser.
Note
For HTML emulation to work, you must have the highest version of the ASP .NET services enabled on the Web Server where you have the Cluster Service running. For example, if you have both .NET Frameworks 1.1 and 2, make sure that the ASP .NET version 2 is enabled.
