Remarks
The PooledPipeline object should be created on each Web page that it is used in instead than being held in Application or Session scope.
Generally, use the PooledPipeline object only in production Web sites; use the MtsPipeline object when you are developing the site. If you use the PooledPipeline object during development, you must stop and restart Internet Information Services (IIS) in order to force the .pcf files to be re-read when you change them.
To create a custom poolable pipeline component, add the GUID 4cb33c86-58fa-4e10-97a8-f19aff3b81d9 to the pipeline component's implemented categories.
The PooledPipeline object is registered under COM+ as "transactions not supported." Use this pipeline if transactions are not needed.
