Virtual Hosts

Assume that a NonStop server has two network names, hp.com, and

internal.hp.com and that NSJSP is required to run applications which use both of

these network names. The applications for both these network names could be

configured to run with the default configuration of NSJSP, which has only one Host

element. However, such a configuration is not flexible enough to separate the two sets

of applications. The use of Virtual Hosts provides the flexibility to define two different

Host elements, each one limited to servicing requests for only one of the networks.

Figure 3-4 illustrates a sample iTP Secure WebServer environment in which a user

accesses different URLs, for example hp.com and internal.hp.com.

The following scenario shows an example of using Virtual Hosts.

In this example, the two URLs are serviced by the same iTP Secure WebServer

environment and the user applications for those URLs are hosted in the same NSJSP

servlet container. The hp.com URL is a public URL and contains user applications that

do not need authentication. The internal.hp.com URL is a private URL and

contains user applications that require authentication. The different types of user

applications need to be segregated so that they can be secured separately. Although

user security can be applied at the individual application level, it is preferable to secure

applications under one secured entity, which is the Host. The virtual hosting feature

enables such a security configuration, which permits the implementation of separate

security constraints for each Host without impacting other Hosts.
