Web Viewer Save - Download method.
What transfer protocol (e.g. FTP, SFTP, etc.) is used by Web Viewer when a user goes in to download / save a report?
When a user initiates a Save Report from Web Viewer, the data is securely http or https (depending on your security) streamed through CA CCI and CA DRAS.
This is a proprietary process and not akin to FTP, SFTP, etc.
