message header

基本解释

Create a message header to contain the requested service level.
創建一個消息頭來包含請求服務級別。
This means that, if the request message in the request mediation flow contains an address in the message header, the request message is sent to the provider at that address.
這意味著，如果請求中介流中的請求消息在其消息頭中包含一個地址，則請求消息將被發送到位於該地址的提供程序。
The logic is primarily based on filtering rules that may be applied on the message content, message header, service requester, and so on to decide the best service provider at run time.
該邏輯主要基於篩選槼則，可以將這些篩選槼則應用於消息內容、消息頭、服務請求者等等，以在運行時決定最恰儅的服務提供者。

They need the ability to encode the message header---the recipient's address---in a new and detectable way.
