Hi Ashok,

Not necessarily.

You mentioned three operations: search, login and buy. These three
operations describe three different message exchanges.

Policies associated with an endpoint policy subject apply to any message
exchange made using that endpoint. 

The Amazon service may have capabilities and requirements that can be
expressed as policy expressions. Requestors may use the effective policy
of the endpoint to determine whether one of the contained policy
alternatives can be met in order to interact with the Amazon service.
Such requestors may choose any of these policy alternatives and must
choose exactly one of them for a successful message exchange. Requestors
may choose a different policy alternative for a subsequent message
exchange. Or, requestors may use the same policy alternative for a
subsequent message exchange.

I hope this helps.

Regards,

In thinking about the above action a question arose and I thought it may
be worthwhile
settling the question before going on to the action.

When I work with Amazon, for example, I may send more than one type of
message.
I may send a few search messages followed by some login messages,
followed by a buy message.
Thus, such a conversation encompasses multiple types of messages.

When endpoints match policies do they match policies for all possible
messages that may occur
in the conversation?  The answer seems obvious but a clarification may
help.

All the best, Ashok
