Subject Throttling by client ID?
Date Wed, 09 Oct 2013 03:11:01 GMT
That is not exactly what the request is about.  It is not throttling only
certain clients. It is throttling all clients but throttling them
individually.  For example, clients cannot send more than 5 requests per
minute per some SLA.
