Define the External Host
The external host is simply the address of the login page. In this example it is www.siebel.com. Be sure to provide a meaningful name in the Virtual Host Name field. This value is used when defining the Symbolic URL definition rather than the actual host name. This will make administration easier if the host name changes. Also notice that there is no value for the Authentication Type. A value is necessary only when using NCSA basic authentication.
Figure 1 shows the external host defined for this example.
