The message (header) or exchange (property) is the right place to "store state" which is related to this exchange/message. Not all protocols support the exchange properties during routing, E.G. for JMS, you have to use the "transferExchange" [1] to not lose your exchange properties (and they must serializable). If you lose your headers, you should have a look at [2].
