New Throttling information is now available

Information about your current throttling usage is now available through the new throttling response headers. APIs that are being throttled will have the following response headers:

X-Current-Token-Count :  The number of requests that will be allowed in the current throttling window 

X-Next-Replenishment-Time : Time at which current window ends and throttling count is reset

For details about throttling, see Throttling in the developer portal guide.
