The Throttling Response Processor returns a response code for Listeners configured with a “Concurrent” Throttling Mode.
Select the Processor Configuration tab and click on Add Processor.
Select the Throttling Response Processor from the drop-down.
On the Basic tab you can specify:
Response Code: The response code for a Listener configured with a “Concurrent” Throttling Mode.
On the Conditional Execution tab, you can set additional Processor execution conditions. The transaction data dependent condition may be specified here as enhanced expression. If this expression returns anything other than TRUE (ignore case) – this processor will be skipped. No additional configuration for this Processor is required.
