About Content Selection Pipelines

Content Selection pipelines are used with the CacheManager object and the ContentSelector object to select content items or other custom content, including discounts.

The advertising and discount delivery engines in Microsoft Commerce Server 2000 are built using Content Selection pipelines. You can create your own pipelines to do different types of content selection.

Two distinct pipelines exist for each content selection application. The first pipeline is responsible for selecting content to be displayed, and is known as the Content Selection pipeline (CSP). It is based on the ContentSelection.pct pipeline-template file. The second pipeline is responsible for processing events related to the displayed content, and is known as the Event Processing pipeline (EPP). An example of such an event is a user clicking on an ad or an ad being selected for display on a page. The pipeline is based on the EventProcessing.pct pipeline-template file.

Note

• Although Content Selection pipelines are used to select discounts, the discounts are not applied in Content Selection pipelines. Discounts are applied to orders by the OrderDiscount pipeline component in an Order Processing pipeline.

The following table shows the CSP stages and the pipeline components provided for each of those stages, for each application.

The following table shows the EPP stages and the pipeline components provided for each of those stages, for each application.
