Would the AWAF parse JSON in a http responses?

Hi;   I know that the AWAF did not do it in version 12. I thought I would ask to see if the JSON data in HTTP responses can be parsed now.     Kindly Wasfi

About logging responses

If you enable response logging in the logging profile, the system can log only responses that include the following content headers:

  • "text/..."
  • "application/x-shockwave-flash"
  • "application/sgml"
  • "application/x-javascript"
  • "application/xml"
  • "application/x-asp"
  • "application/x-aspx"
  • "application/xhtml+xml"
  • "application/soap+xml"
  • "application/json"

The system cannot log other responses.

 

If your response have the "application/json" then system should log the response.

 

The manual for v12.1.x says the same.
