The HTTP Response Headers Processor adds headers to the stored headers attribute for HTTP response headers.
Select the Processor Configuration tab and click on Add Processor.
Select the HTTP Response Headers Processor from the drop-down.
Headers: Allows specification of HTTP header name-value pairs to use in synchronous response.
In 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 further configuration for this Processor is required.
