The Redirector

The Redirector is a service that runs on the Host On-Demand server and that allows a Host On-Demand client to communicate with a Telnet server by connecting to a Redirector port on the Host On-Demand server.

Normally, a Host On-Demand client:
  • Connects directly to the Host On-Demand server to download the client code and to access public HTML files.
  • Also connects directly to a Telnet server that runs on or is connected to a 3270, 5250, VT, or CICS host.

However, when the Redirector is used, the Redirector acts as an intermediary between the client and the Telnet server. The client, instead of connecting directly to the Telnet server, connects to a Redirector port on the Host On-Demand server. The Redirector then sends to the Telnet server the data received from the client. When the Telnet server replies, the Redirector sends to the client the data received from the Telnet server. This process continues until the session ends.
