well-known or trusted to the Redirector. You can add certificates from other

Is created and updated during SSL configuration. This database contains
server and CA-root certificates that are not in the well-known list and are
needed by Host On-Demand clients.
Examples of when to use SSL security
Some situations where you might want to use SSL security include:
v You want to let customers order your products over the Internet. You want to
make sure information they give you, such as a credit-card number, is encrypted
so that it cannot be stolen. You also want to make sure information you give to
customers is protected.
v You want to give your suppliers or business partners access to certain
information on your host computers and to be sure that the data is not available
to anyone else.
v You want your staff to have access to your host-computer information from
remote sites or when they are traveling.
v You are a hospital administrator and want doctors to have access to patient
records from wherever they are and to be sure that the records cannot be seen
by unauthorized people.
Using the Redirector
On Windows NT and AIX, the Redirector provides support for Secure Sockets
Layer (SSL) security between clients and the Host On-Demand server.
The Redirector acts as a transparent Telnet proxy that uses port remapping to
connect the Host On-Demand Server to other Telnet servers. Each defined server
can configure a set of local-port numbers. Instead of connecting directly to the
target Telnet server, a client connects to the Host On-Demand server and port
number. The Redirector maps the local-port number to the host-port number of the
target and makes a connection.
Redirectors can be connected to each other (in a cascaded configuration). In that
case, SSL security is also available between the redirectors (Windows NT and AIX
only).
How the Redirector works
The following scenario shows how the Redirector works. Secure connections are
possible between the client and Host On-Demand server.
