Biztalk Pipeline Question:

A receive port is a collection of one or more receive locations that define specific entry points into BizTalk Server. A receive location is the configuration of a single endpoint (URL) to receive messages. The location contains configuration information for both a receive adapter and a receive pipeline. The adapter is responsible for the transport and communications part of receiving a message. Examples include the File adapter and SOAP adapter, each of which receives messages from different types of sources. The receive pipeline is responsible for preparing the message for publishing into the MessageBox. A pipeline is a series of components that are executed in sequence, each providing specific processing to a message such as decryption/encryption, parsing, or validation.
