The file proxy server is used for unifying processing authority and interactive modes and unifying a common interface mode to shield differences of interactive modes such as FTP/SFTP/SOCKET/file stream and the like and internally unifying the modes of the file stream. The file proxy server belongs to an external network partition (DMZ/PTR) area. The DMZ zone is an external gateway zone, which is a dangerous area because of the complex network environment, where the file needs to be safely scanned to transfer the file to the SF zone. The PTR zone is similar to the DMZ zone, but because it is a private line, facing a particular party of relevance, the risk factor is greater than the SF zone, but smaller than the DMZ zone. The DMZ and PTR domains cannot be directly connected and need to be transferred through the SF domain.
