Remarks
The OrderPipeline should be used in Content Selection pipelines because Content Selection pipelines do not require transactions and because the OrderPipeline object is fully re-entrant by multiple threads. Other objects, such as MtsPipeline and MtsTxPipeline, must be used once, destroyed and recreated by each thread due to the rules of COM+ transactions.
The OrderPipeline object can create and run Content Selection pipelines or Order Processing pipelines (OPP); however, it is recommended that you use the OrderPipeline object only to create and run Content Selection pipelines. The OrderPipeline object is the only pipeline object that is not registered under COM+ Services.
The OrderPipeline object is usually created in the file Global.asa and put into an application collection.
