Nodes and URL
Nodes and the URL property work together and are interrelated. The node is how to ‘register’ a logical name for a Web server (the Web server name, on the servlet, and so on) not the actual details. This way, content references don’t change when a Web server changes.
For example, suppose you had content that you referenced on the HRMS Web server. However, the machine name for that server changed. You can change the URI of the Node, instead of changing every content reference that referred to that content.
At least one node must be specified as the default local node. Nodes are also required for PeopleSoft components and iScripts.
Considerations When Using Nodes and the URL Property
When a content reference is created it is ‘registered’ with its URL (the portal, and others, typically find a content reference by its URL). The node is used to create a logical name for the Web server, servlet, and so on, so these details are not included in a content reference’s URL. When details of a Web server change, such as at installation time, only the URI for the content provider must change. You don’t have to change the URL for any content references.
When the node is specified, the content provider’s URI is concatenated with the URL property.
The format of the URL property depends on the content it's pointing to.
