This information was already available, however located in the REQUEST HEADERS section, making it more difficult for users to distinguish the 2 types of information.

  • Response Max Size Setting Updates

    • The default value of this setting has been increased from 500Kb (500,000) to 5Mb (5,000,000) to take into consideration modern web applications bundling their Javascript into large files that could have been truncated with the previous value. This setting has also been available to PCI WAS scans templates.

      Note: This setting cannot be set a value lower than 500kb (500,000).
