In same cases, it's required to save the request/response for certain purposes, such as debugging, auditing, etc.

There are few ways to save request/response, such as using "Audit Messages in Policy" assertion and select always save request/response, or using "Add Audit Detail" assertion to save ${request.mainpart}/${response.mainpart} ...
For exporting request/response in audit tables, please refer to KB000113701 ( https://knowledge.broadcom.com/external/article?articleId=113701 )

NOTE1: If the ${response.mainpart} is not set due to exception in the service policy, the response body will be empty. ie. the traffic log may not be able to save default/custom error response.
NOTE2: The new log file can be found under folder /opt/SecureSpan/Gateway/node/default/var/logs
NOTE3: The traffic log output can be customized in cluster wide property trafficlogger.detail, the above is just an example,  the format can be changed, or add more context variables.
The output of above setting may look like,
