FTP Proxy Settings
Settings for running a proxy on an appliance under FTP.
When a file is uploaded to the web from an FTP client and processed on Web Gateway, you can send progress indicators to the client by inserting the FTP Upload Progress Indication event into a suitable rule.
This will prevent a timeout on the client when processing takes more time, for example, due to scanning the file for infections by viruses and other malware.
